Gas is being pumped into a spherical balloon at the rate of 30 ft3/min. Then, the rate at which the radius increases when it reaches the value 15 ft, is
- \(\frac{1}{\boldsymbol{\theta} \pi} \mathbf{f} / \min\)
- \(\frac{1}{5 \pi} \mathrm{f} / \mathrm{min}\)
- \(\frac{1}{0} \mathrm{f} / \mathrm{min}\)
- \(\frac{1}{\mathfrak{D}} \mathfrak{f} / \min\)
