PLEASE HELP, VERY CONFUSED WITH THE CONTEXT OF THE QUESTION !!!! Square Root Equations

Question

The radius r (in inches) of a ball is given by r=✔️S/4π ( under the radical), where S is the surface area (in square inches) of the ball. Use the trace feature of a graphing calculator to find the least whole number value of S at which the radius exceeds 5 inches.

Answer 1

r = √(S / 4π) formula

5 < r giiven condition

5 < r = √(S / 4π)

5 < √(S / 4π)

25 < S / 4π

100π < S
