Question
Assume that the radius \( r \) of a sphere is expanding at a rate of \( 10 \, \text{in./min} \). The volume of a sphere is \( V = \frac{4}{3} \pi r^3 \).

Determine the rate at which the volume is changing with respect to time when \( r = 5 \, \text{in.} \)

The volume is changing at a rate of \(\boxed{\phantom{0}}\) \(\text{in}^3/\text{min}\).
