Question

Find the circumference of a a circle with an area of 530.93 square meters

Answer 1

The circumference is 26$\pi$

To find this we must start by finding the radius of the circle. You can find this using the formula for area adjusted to find the radius.

r = $\sqrt{ \frac{A}{ \pi }}$

Then when we plug the area in for A, we get the radius to be 13. 

We can then use that number in the circumference formula which is below. 

C = 2$\pi$r

Using that we can find the circumference to be 26$\pi$
