What is the radius of a circle with an area of 78.5 cubic inches? Use 3.14 for pi. Enter your answer in the box.

r = 5 in

Step-by-step explanation:

Area of a circle is given by

A = pi r^2

We know the area and pi

78.5 = 3.14 r^2

Divide by 3.14

78.5/3.14 = 3.14 / 3.14 r^2

25 = r^2

Take the square root of each side

sqrt (25) = sqrt (r^2)

5=r
