Answer:

The area formula pi r2, so pi r2 = 113.04. Divide 113.04 by 3.14, and you get r2 = 36^2=6

Explanation

Area of circle = πr^2 , where r is the radius of the circle

= > πr^2 = 113.04 sq. inches

= > 3.14 x r^2 = 113.04 sq. inches

= > r^2 = 113.04 / 3.14 sq.inches

= > r^2 = 36 sq. inches

= > r = 6 inches

r or radius of the circle is of 6 inches.
