We can use the formula r=squareroot s/12.6 to relate a ball's surface area (in square inches) to its radius (in inches). suppose a ball has a surface area of 390.6 square inches. what is its radius? round your answer to the nearest tenth.

The radius is 5.56 inches.

Explanation:

Given that,

Surface area = 390.6 inch²

We need to calculate the radius

Using given formula

S = surface area

r = radius

Put the value of S in to the formula

Hence, The radius is 5.56 inches.
