Answer: 6 inches.

Explanation:

1. You must use the formula for calculate the area of a circle, which is shown below:

A=3.14r^(2)

2. You know the area of the circle, therefore, you can solve for the radius, as following:

$3.14r^(2)=A\\r^(2)=(A)/(3.14)\\r=\sqrt{(A)/(3.14)}$

3. Now, you must substitute the value of the area into the equation above. Then, you obtain the following result:

$r=\sqrt{(113.04in^(2))/(3.14)}\\r=6in$
