Question

What is the area for this problem?

Answer 1

It's 324pi since the circumference is 2 pi r, you can divide 36 by 2 to find the radius, after finding the radius plug it into the area equation which is pi r^2

Answer 2

C = 2* pi *r = 36 pi

 r = 36pi/2pi = 18

We know that A= r^2 * pi

A = 18^2 * pi = 324 pi

the area would be 324PI square units
