im trying to figure out the area of the overall shape
i need to figure out the yellow part,,,
i have the measurements but im failing wtf please help its due tomorrow

mellow lark
#

Could you share the measurements please?

#

Also breathe.

narrow scroll
#

OMG okay so like

pure violet
#

I guess this is logo of google Adsense

narrow scroll
#

maybe idk..

#

so uhm the blue shape is like

#

here i

#

put it on another thread i have the stuff

pure violet
#

Total area....or whatever info you have pls....

narrow scroll
#

im trying to figure out the area 😭 there was a hand written version

#

Outside Yellow Line is 11cm
Inside Yellow line is 6.3cm
Outside Blue Line is 11.5cm
Inside Blue line is 6.3cm
The Green circle is 8.64cm with a radius of 2.75
The Blue stick also has like

#

and so the area of the green shape is

pure violet
#

OHhhhhh

narrow scroll
#

17.27875959cm2

pure violet
#

Ok

narrow scroll
#

im trying to figure out yellow's area

pure violet
#

Wait

narrow scroll
#

and like stuff like that

#

im so sorry im so bad at explaining

pure violet
#

Ok i understand

#

Same with me....

#

Haha

narrow scroll
#

i just need to know like

#

the theory or

#

formula

#

to figure out its area

#

i can figure out the numbers then sorta if i have that

#

OKAY WAIT

#

HERE I HAVE MORE INFO

pure violet
#

What is ur grade....

narrow scroll
#

9..

mellow lark
pure violet
#

A sum is not supposed to be so calculative.....i am grade 8

narrow scroll
#

what

pure violet
#

But i can do ur stuff

#

Which country

#

Are u from....

#

Me from India

narrow scroll
#

im from australia

pure violet
#

Ohhhhh

#

Are sums too tough there....

narrow scroll
# mellow lark

C1 = Semi Circle Green – 5.5cm in diameter, 2.75cm in radius. To figure out circumference.
c=2πr . c=2 x π x 2.75cm =17.28cm ÷ 2 = 8.64cm

C2 = Semi Circle Blue
c=2πr . c=2 x π x 2.75cm =17.28cm ÷ 2 = 8.64cm

C3 = Quarter Circle Blue
θ/360 x 2πr d=144/360 x 2 x π x 2=6.911

Y1 = Outside Yellow Line = 11cm

Y2 = Inside Yellow Line = 6.3cm

B1 = Outside Blue Line = 11.5cm

B2 = Inside Blue Line = 6.3cm

#

AND...

pure violet
#

......

mellow lark
#

To put it simply.

#

Ew.

narrow scroll
#

is this like

#

not understandable

mellow lark
#

No it is it's just yucky.

#

Area right? Not perimeter?

narrow scroll
#

yea

#

im supposed to figure out its area.

pure violet
#

The yellow part is just a rectangle

narrow scroll
#

its not though..

mellow lark
#

They don't overlap?

narrow scroll
#

nope

pure violet
#

Without a semicircle and a triangle

narrow scroll
#

theyre all seperate

pure violet
#

Bruh when do you have to submit...

narrow scroll
#

oh it was due 3 days ago

#

but i had atechnical issue

#

so im gonna show him this mroning around

#

idk

pure violet
#

I mean your school timing

narrow scroll
#

9 hours

pure violet
#

Ooooo

narrow scroll
#

@mellow lark is this like impossible

pure violet
#

How much time do you have

#

I mean to just solve the problem

narrow scroll
#

oh theres more stuff

#

uhmm i can bullshit alot

#

but probably today its due

mellow lark
#

Give me a second.

#

Those are semicircles on the blue?

#

Congruent to the green?

narrow scroll
#

uhm the top of blue is a quarter circle

#

the green is a full circle

#

and on the bottom of blue is a semicircle

#

the quarter circle has a is 144/360 angle or theta IDK

#

help

#

okay uhm but i figured out

mellow lark
#

Yes?

narrow scroll
#

C1 = Semi Circle Green – 5.5cm in diameter, 2.75cm in radius. To figure out circumference.
c=2πr . c=2 x π x 2.75cm =17.28cm ÷ 2 = 8.64cm

C2 = Semi Circle Blue
c=2πr . c=2 x π x 2.75cm =17.28cm ÷ 2 = 8.64cm

C3 = Quarter Circle Blue
θ/360 x 2πr d=144/360 x 2 x π x 2=6.911

Y1 = Outside Yellow Line = 11cm

Y2 = Inside Yellow Line = 6.3cm

B1 = Outside Blue Line = 11.5cm

B2 = Inside Blue Line = 6.3cm

11cm + 6.3cm + 11.5cm + 6.3cm + 6.911cm + 8.64cm + 8.64cm = 58.791 perimeter
this much!

mellow lark
#

Perimeter is not needed unfortunately.

narrow scroll
#

oh..

#

what do u need

#

i can help with it

#

if i can figure out

#

its total area i can subtract

#

the blue and green to find yellow

#

but i need to find blue first

#

which seems easier

#

okay wait here i have a thingy

pure violet
#

40.92cm2 estimated...

mellow lark
#

What is the angle of the sector?

pure violet
#

I think this is good to go....

mellow lark
narrow scroll
#

the sector is the blue quarter?

#

no i figured it out

mellow lark
#

Yes.

#

Ah.

#

Quarter.

narrow scroll
#

its 144/360

#

OH

#

uhm

#

hold on..

#

im

#

LETS NOT SAY QUARTER

#

ITS NOT A QUARTER

#

ITS THE SHAPE OF IT

pure violet
#

40.92 cm2 or die

narrow scroll
#

its 144

#

okay wait uhh

mellow lark
#

How do you know?

pure violet
#

Yellow part is 40.92

narrow scroll
#

wait how

#

did u figure that out

pure violet
#

Can i message you clearly .....

#

After a minute

narrow scroll
#

alright

#

okay uhm i need paint

pure violet
#

My work is a bit lot messy

#

Paint??????!!!!

#

Just a big tough rough work please

#

So as mj gave....

narrow scroll
#

WAIT

#

OMG

#

IT DIDNT

#

FUCK

mellow lark
#

I can solve it if I know the angle of the sector.

pure violet
#

Oooooooo9oooooooooooooooooooo

#

Jhhhgyffhhhhgyhh

#

Jhhhgyffhhhhgyhhhgg

#

Hhg

#

Gg

#

Ggb

#

Sorry i spammed....

narrow scroll
#

and

narrow scroll
#

the lines on blue are the diamater of the semi circles if u see it that way too

#

i put two lines showing

#

the angle of the sector

#

and if it was a

#

semi circle

#

it would be 5.5cm

mellow lark
#

How do you know?

narrow scroll
#

i measured it

#

he gave us a paper copy

#

that was the basis

pure violet
#

Same....

mellow lark
#

Were you supposed to measure it?

pure violet
#

Concept is the same....

mellow lark
#

Just making sure.

pure violet
#

No neeed of using full decimals....

#

Just use estimates....

#

Class 9 starting bro.

#

You will be mercied

narrow scroll
narrow scroll
pure violet
#

Oooo

#

Anyways....no diff if you take estimate

mellow lark
#

144/360 makes no sense.

pure violet
#

Yep

narrow scroll
#

wait it doesnt

mellow lark
#

That means the angle is 40 degrees and it's an obtuse angle.

narrow scroll
#

?

pure violet
#

Why make things so complicated

narrow scroll
#

i feel like i mis said so many things

mellow lark
#

Yeah probably.

#

If you get the angle let me know.

#

Otherwise I have to do my own work.

narrow scroll
#

how would i.. theoretically

#

figure that out

pure violet
#

Just visualise sums...

mellow lark
#

Here's a hint.

narrow scroll
#

how did u guys figure out those numbers..

pure violet
#

As is said the yellow part is nothing but a rectangle....without some parts

narrow scroll
#

yea but it doesnt overlap so i ahve to subtract it

pure violet
#

White is area....i suppose.

#

Bruh

narrow scroll
#

pylover

#

can u help me ill literally do anything,,

pure violet
#

What do you mean by doesnt overlap....

pure violet
narrow scroll
#

its all together right but

#

where it seems like

pure violet
#

Join my grp

narrow scroll
#

yellow seems like its a rectangle covered by those two shapes right?

#

but yellow is actually just that shape

#

but knowing that its a rectangle can help

#

okay wait

#

uhm

#

to figure out yellow i would have to

pure violet
#

Okkk

narrow scroll
#

subtract those numbers

#

i think

#

wait

#

BRO

#

im

pure violet
#

Youre

narrow scroll
#

okay i think i made a mistake

#

trying to figure out

pure violet
#

Shaded part is yellow.....rectangle

narrow scroll
#

the sector

#

how would i figure out the angle of the sector?

pure violet
#

The shaded part might help....

#

No need of sctor

narrow scroll
#

what??

#

can u explain how i could do that

pure violet
#

The length of the yellow outer part is 11cm

narrow scroll
#

yes

pure violet
#

The diameter for green circle is the breadth for the yellow rectangle.

narrow scroll
#

breadth?

#

is that width?

pure violet
#

See my pic.....

#

The shaded part there is your yellow rectangle.....to be supposed

narrow scroll
#

yea the diameter of the green circle is 5.5

#

and so the width of the yellow rectangle would be 5.5?

pure violet
narrow scroll
#

okay so

#

and the

#

length is 11cm

#

5.5 w / 11 l

#

which is 60.5cm2

pure violet
#

Yep...

narrow scroll
#

and then in blues case its rectangle

#

without the semi circles / sector

#

would be

#

11.5cm length x 5.5 width

#

63.25cm2

pure violet
#

The area of the green circle inside the yellow rec is 11.8 estimate

narrow scroll
#

and then the semi circles would be

pure violet
#

Blue part not reqd

narrow scroll
pure violet
#

Oh no estimate

narrow scroll
narrow scroll
pure violet
#

5.5/2

#

Is the area

narrow scroll
#

what

#

is /2 divide or square

#

okay so blues area i mpretty sure is 23.76 + 63.25

pure violet
#

Divide

narrow scroll
#

blue has a total area of

#

87.01

#

green has a total area of

pure violet
#

Total area or only the yellow part is reqd

narrow scroll
#

23.76cm

narrow scroll
#

do u mean requested?

pure violet
#

Bruh sorry....i have to exit.....its so late here...

narrow scroll
#

oh

#

alright

#

theres a total of 6 questions

#

its this thing i have it on a file

#

hopefully someone can help

#

DESPERATE HELP PLEASE SPAM PING ME

#

OKAY SO green area and blue area together is 110.77cm, to find out the total area and yellow i would have to.

#

okay wait

#

@mellow lark i haev a question if u could answer if ur free

mellow lark
#

Mhm?

narrow scroll
#

its not a quarter circle, but more closer to a semi circle

#

the sector

#

its 144/360 and it is an obtuse angle

#

im pretyt sure thats right

#

so

#

u said like

#

u said the angle would be 40 degrees but

#

its not..

#

the angle is 144 degrees

#

?

mellow lark
#

So it's just 144.

narrow scroll
#

yea

mellow lark
#

Okay that helps.

narrow scroll
#

wait

#

OMG

#

I NOTICED IT

#

OHH

#

144/360 i didnt mean divison

#

i meant like

#

its 144 degrees over 360 total degrees

#

😭

#

wait what can i use the angle for though?

mellow lark
#

What is 36 degrees in radians?

narrow scroll
#

radians?

#

wait i need to google what that means

#

im so sorry

#

okay i think i know how to figure out the area instead of subtracting

#

it doesnt need to be exact but

#

if i can figure out

#

the triangles depicted from the red lines

#

i can solve this

#

because those triangles i made are all the same size (measured and confirmed with teacher)

#

i also saw him doing it and said it would work

#

so i think

#

im just gonna make it straight even if itsn ot

#

but like

#

ur way is probably more accurate

#

i just need to figure out what a radian is

narrow scroll
#

just this?

#

or do u mean like

#

what would it be

#

as a radian expression

#

0.628319

#

thats what it would be in radians

#

36° × π / 180°
= 0.2π rad
= 0.62831853072 rad

mellow lark
#

Good that's what I needed.

#

Multiply that by the radius and you have the area of the sector which you add the the parallelogram beneath it.

#

Find the area of the yellow rectangle. To that, add half of the green circle's area to account of overlap.

#

Let me finish, I'm not helping after this.

#

Find the area of the blue rectangle. Add that to the areas of the two semicircles on the ends. Now add this with

mellow lark
#

From all of that, subtract

narrow scroll
#

so i multiply 0.62831853072 by 2.75cm which is the area of the sector?

mellow lark
#

Wait no no

#

The area of a sector is 144/360 times pi 2.75^2

narrow scroll
#

ohh

#

and then the sector to its left

#

is 36/360 times pi 2.75^2

#

THANK YOU

mellow lark
#

Exactly.

narrow scroll
#

i was gonna try and figure out the area of these but this way

#

seems more

#

whats it called

#

accurate

mellow lark
#

No ew that is beyond your capabilities.

#

That's calculus.

narrow scroll
#

oh

#

well i got

#

9.50

#

9.50331

mellow lark
#

Cool, follow the rest of the directions and you should be good.

#

I'll be on my way.

narrow scroll
#

from doing 144
----- times pi times 2.75 to the power of 2
360

#

thats what u meant right?

narrow scroll
mellow lark
#

Thank you, good luck.

narrow scroll
mellow lark
#

Mhm.

narrow scroll
#

OH YEA NO WORRIES

#

thank u

mellow lark
#

Here let me simplify.

narrow scroll
#

alright

mellow lark
#

Add A, B, D, E, and D2.

#

Subtract C and F.

narrow scroll
#

alright

#

ill have to do more measurements

#

thank u

mellow lark
#

Mhm.

<@&776327020388679680>

last mountain
#

@narrow scroll found it

narrow scroll
#

hi

#

so like practically

#

i have to find the area of this shape

#

ive been stuck on this question for a few hours.

#

i know most measurements

last mountain
#

Wait can you label angles ?

narrow scroll
#

what

#

sorry

#

label which angles

last mountain
#

Angles of the kite or above the kite

narrow scroll
#

oh uhm

#

so above the kite

#

the two sectors

#

the smaller one has an angle of 36 degrees

#

the bigger oen has a 144 degrees

last mountain
#

Upper 144

narrow scroll
#

yeah

#

144 is the upper one

#

we figured out its area is

#

9.50

#

cm2

last mountain
#

Aight or kite's top has 144

narrow scroll
#

wait

#

i have to figure out the kites angle too..

last mountain
#

Ye

narrow scroll
#

isnt it just 144

last mountain
#

The sides

narrow scroll
#

.

#

can u do it lol!!

last mountain
#

This is gonna take ages despair

last mountain
narrow scroll
last mountain
#

Kite

narrow scroll
#

maybe

last mountain
#

And right to left ?

narrow scroll
#

no im crying

#

😭

#

why the fuck is this so hard

#

can we get mj back here

#

ill buy them nitro

#

if they figure this out for me 💔

last mountain
#

😂

#

I think you should actually sleep now, and we get flr tomorrow morning

#

Or mj

narrow scroll
#

im staying up

#

i have to

#

its due 3 days ago

#

but i had technical issues

#

so im doing it now

last mountain
#

☠️

narrow scroll
#

and bullshitting my way

#

SO PLEASE

#

CAN U HELP ME

#

ILL BE UR SLAVE

#

OR WTV

#

WHY THE FUCK AM I ASIAN AND SHIT AT MATH

#

@last mountain BRO

#

WERE BOTH WRONG

#

IT CAN BE VIEWED AS QUADRILATERIAL

#

INSTEAD OF A KITE

#

AND IT WORKS

#

too

last mountain
narrow scroll
#

wgatg]

#

what..

last mountain
#

A parallelogram is quadrilateral too

narrow scroll
#

im kms

#

💔

#

why is math so hard

clever storm
#

In which grade are you in

narrow scroll
#

9

#

why..

clever storm
#

.

#

Nothing

narrow scroll
#

IS THIS

#

no tell me 😭

clever storm
#

What did you guys find

narrow scroll
#

I CANT FIND SHIT

#

HOW DO I FIGURE THIS OUT

#

IVE BEEN AWAKE FOR 5 HOURS DOING THIS

#

AND THATS ALL IVE DONE SO FAR

clever storm
#

And do you have to type the answer or MCQ

narrow scroll
#

mcq??

#

omg all these terms..

clever storm
#

Are you given options

#

Like a b c d

narrow scroll
#

waht

#

no i had to make the letters up

#

@clever storm

#

do you know to figure out the area of this kite

#

or like whats missing to figure it out

clever storm
#

Divide it into 2 right angled triangles

narrow scroll
#

yea then?

narrow scroll
#

okay wait

#

so would both right angled triangles be

clever storm
#

Not sure about the second one

narrow scroll
clever storm
#

What's radius of the semi circle above

narrow scroll
#

they are two sectors

#

oh

#

OHH

#

M

#

MB

#

sorry

#

the radius is 2.75

narrow scroll
clever storm
narrow scroll
#

i timed 6.4625

#

by 2?

#

times*

clever storm
#

Yes

narrow scroll
#

REALLY?

#

I LOVE YOU

#

OMG

#

BRO IM FINALLY DONE THIS QUESTION

clever storm
#

Wait I just wanna confirm

narrow scroll
#

alright

clever storm
#

Yeah

#

Its correct

narrow scroll
#

ALRIGHT

#

CAN I ADD U

#

UR SMART

clever storm
#

Lol add MJ

#

He did all of the work

narrow scroll
#

mj isnt online

#

and left

#

i tried to add them

#

but theyre not accepting

clever storm
#

I am still wondering how can they give a ninth grader this question

narrow scroll
#

is this like not possible

#

for a ninth grader

#

or like is advanced or is it lower

clever storm
#

Idk the syllabus at your place

narrow scroll
clever storm
#

But it's a bit too big

narrow scroll
#

like

#

hard?

#

or just too vague

clever storm
#

I mean a person with a little bit more than basic knowledge about properties of quadrilaterals can only solve this question

narrow scroll
#

so im stupid..

#

😭

clever storm
#

No

#

I mean

narrow scroll
#

its okay

#

im willoing to accept i am

clever storm
#

Maybe syllabus at your place is different

narrow scroll
#

fuck u australia

clever storm
#

I am just comparing it with what I have studied in grade 9

narrow scroll
#

WAIT

#

ARE U FINISHED SCHOOL?

clever storm
#

I have finished that grade

narrow scroll
#

@clever storm

clever storm
#

Yeah

narrow scroll
#

do you know how to figure out percentages next

clever storm
#

Can you give the question

narrow scroll
#

What percentage of the total area is the green, the blue and the yellow?

#

Yellow ( 33.4cm^2) + Green ( 23.76cm^2) + Blue (87.01cm^2) = 144.17cm^2 in total

#

is my results

#

so all i have to do is like

#

33.4cm / 144.17cm x100?

#

and the same for the others?

clever storm
#

Yeah

narrow scroll
#

i justn eed ur confirmation

#

ur older and smart

clever storm
#

My geometry is pretty weak

narrow scroll
#

are u in america

clever storm
#

Nah

narrow scroll
#

oh

#

okay im about to use geogebra

narrow scroll
#

I FINISHED IM SO PROUD
