Explanation:

$Circumference = 2r\pi \\Area = r^2\pi$

In order for us to find the circumference, we need to find the radius from the given area by rearranging the area formula.

$r=\sqrt{(A)/(\pi ) }$

$r=\sqrt{(113.1)/(\pi ) }$

r=√(36)

r=6

Now that we have the radius, we can find the circumference.

$Circumference=2(6)\pi$

$Circumference=12\pi$

Circumference=37.68

So, when given 113.1 in sq for the area, the circumference of the circle is 37.68 in.
