Question

What radius of a circle would guarantee that the circumference is equal to the perimeter of a regular octagon with sides of 6? Use 3.14 for Pi.

Answer 1

What is the perimeter of the octagon?

Answer 2

(r=radius of circle) 2*r*pie= 6*8 (perimeter of octagon). then solve from there.

Answer 3

It doesn't say...But the answer choices are: A)5.5 B)6.4 C)7.6
or D)8.2

Answer 4

the total premeter of the octagon is 48

Answer 5

2*r*pie= 6*8 then r=24/pie which equals C) 7.6.

Answer 6

Oh for heaven's sake. Why don't you guys let the asker answer the questions of someone who is trying to help her understand?

Answer 7

Yea someone please explain evenn I dint egt this one

Answer 8

Thank you! :) but I still don't get how you got it lol

Answer 9

I also got c) 7.6 and can explain if you need help @purenova

Answer 10

We can use a formula to find this answer
First of all we know that the total premeter of the octagon is 6*8=48
Now we use the circumfrence to find the answer
the total circumfrence has to be 48
so
2pi r=48 --- solve for r
6.28 * r = 48
48/6.28=r YAAAY
