multi step problem with perimeter

[gentle jacinth]

I haven’t covered this yet 😓

pls don’t laugh

[fallen finch]

Okay so if I remember correctly basically all you do is find the area of the square

[gentle jacinth]

60

[fallen finch]

So 12 X 5=60

[gentle jacinth]

Is that all

[fallen finch]

No

Wait actually I don’t think I am correct

Give me a minute

Okay I got it now

So what you do is you treat the area like a full circle

So the diameter is going to be 12

The area of a circle is Pie R squared

A = Pie R squared

= pie X 6 squared (half of the diameter it’s called the radius)

= pie x 36 (here we have just squared the 6)

= 113.09

Because we worked it out as a full circle we then must divide it by 2

Sence it’s a semi circle

[gentle jacinth]

Ahhh

[fallen finch]

56.545

Does that help ?

Oh wait we still got the money part

[gentle jacinth]

Yesyes Im gonna give it a go and let you know what I got

[fallen finch]

Okay

[gentle jacinth]

Yea I forgot about that money part

That shouldn’t be too hard tho

[fallen finch]

No you should be alrigth

[wide tundra]

u shouldnt be calculating area at any point

[opal bramble]

Fr

It’s perimeter

[daring grail]

^

calculate the circumference of that half of the circle and then the perimeter of the recntangle but only the sides that will have fence (5 + 12 + 5 basically) bc there is one area of lenght that wont have a fence

[rustic lynx]

Yeah it’s not area it’s perimeter

[pearl dirge]

find the perimeter of the rectangle (that doesn't include the diameter of the semi circle) then find the circumference of the semi circle add them together then multiply it by 3

[strange vault]

You need to find the circumference of half the circle
