Question

If the area of a circle is 36 pi, what is it's circumference?

Answer 1

the answer is 12*sqrt pi

Answer 2

C = 12π or 37.7

Explanation:

A = πr²

36π = πr²

π's get divided out and you are left with:

r² = 36

if you take the square root of 'r' it will equal the square root of 36, which is 6

C = 2πr

C = 2π(6)

C = 12π or 37.7
