Answer 1

What's the total perimeter of the octagon?

Answer 2

How many sides does and octagon have?

Answer 3

omg i get what you're asking now duh

Answer 6

?

Answer 7

Answer 8

So what's the next step?

Answer 10

Show me how you'd do it.

Answer 11

Never mind I just lost myself. i think you plug the 8 in for the radius

Answer 12

I suck at math if you havent noticed :/

Answer 13

An octagon with 8 sides of length 6 each. What's the total length of all the sides?

Answer 14

And stop saying you suck at stuff. Nobody's perfect.

Answer 15

I need you to make an attempt.

Answer 16

14 ?

Answer 17

How did you get that?
If there are 8 sides each of length 6, what's the total length?
So you have 8 boxes.Each box has 6 yoga pants in it. How many yoga pants do you have altogether?

Answer 18

so 48 ?

Answer 19

Yeah, so 48 is the perimeter of the octagon.
Now how would you find the perimeter of a circle?

Answer 20

2 pi r

Answer 21

You want the perimeter of the circle to equal that of the octagon.
So 2pi*r = 48.
How would you find r?

Answer 22

i guess divide 48 from the 2*pi ?

Answer 23

Yes.

Answer 24

So you see it's not that bad.
