How to find area and perimeter of this werid ah shape

[burnt trellis]

1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
2. Wait patiently for a helper to come along.
3. Once someone helps you, say thank you and close the thread with:

   +close
   

4. Feel free to nominate the person for helper of the week in #helper-nominations
5. Do not ping the mods, unless someone is breaking the rules. If there is a conflict amongst multiple helpers feel free to ping “Helper Mod”
6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

cut it up into three semicircles

hint: one of them will be a hole

i tried

i think i got it wrong

cause my perimeter is larger than my area

why shouldn't it be?

oh

i got

area= 12.57m^2

perineter= 21.13m

[tropic timber]

i seem to have a different answer

oh

what did u get

approximately 6.28

how did you obtain your area?

Area of Circle = (Radius)^2

Area of Circle = (Radius)^2

Area of Circle = (2 m)^2

Area of Circle = 4 m^2

Area of One Sector = 1/2 Area of Circle

is there latex on this sever

yes

\text{Area of One Sector} = \frac{1}{2} \times 4\pi , \text{m}^2

[tropic timber]

you mean π(radius)^2?

ye

latex tweaking

[tropic timber]

enclose in $dollar signs$

a lot of people

[tropic timber]

$\text{Area of One Sector} = \frac{1}{2} \times 4\pi , \text{m}^2$

Onyx

[tropic timber]

$\text{Area of One Sector} = 2\pi , \text{m}^2$

[paper terrace]

Onyx

[tropic timber]

Now The circumference of the circle

$\text{Circumference} = 4\pi , \text{m}$

[paper terrace]

Onyx

[tropic timber]

$\text{Arc Length of One Sector} = \frac{\text{Circumference}}{2}$

[paper terrace]

Onyx

[tropic timber]

$\text{Arc Length of One Sector} = 2\pi , \text{m}$

[paper terrace]

Onyx

[tropic timber]

$\text{Perimeter} = 2 \times \text{Arc Length of One Sector} = 4\pi , \text{m}$

ok slow down

ok

[tropic timber]

this is the area of what, exactly?

1 sector

wiat hold on

i think im special

[tropic timber]

what's a sector

or, specifically, which sector

the half circle

waittttt

for the area

cant i just calc the area of a half circle with the raduius 2m?

i got 6.28

ong im special

idk perimaeter

[tropic timber]

yes

[tropic timber]

you're going to have to split it up into three arcs

hm ok

is the perimeter of the big arc 6.285

i got 12.56 for the perimeter

am i cooked? or cooking

[tropic timber]

6.285?

ya

how did you get that

2pir

r=2

and then take half

C=2πr=2·π·2≈12.56637

12.56637/2

so 2π?

6.283185

[tropic timber]

that's not 6.285

that's 6.283 with rounding

damm ok

so its

uh

and yes, that is the perimeter of the big arc

i still get 12.566

i assume you have found the two smaller ones in a similar fashion?

ye

[tropic timber]

seems about right

ok

ty

acuatlyy

nah ill do dis tmr

i gotta go be batman

[tropic timber]

ty for help
