Find the rate of change of radius of a sphere when its radius is \( 4 \mathrm{~cm} \) and when its volume is changing
P at the rate of \( \frac{4 \pi}{625} \mathrm{~m}^{3} / \mathrm{sec} \).
(1) \( 1 \mathrm{~m} / \mathrm{s} \)
(2) \( 2 \mathrm{~m} / \mathrm{s} \)
(3) \( \pi \mathrm{m} / \mathrm{s} \)
(4) \( 3 \mathrm{~m} / \mathrm{s} \)
