A spherical snowball is melting in such a way that its volume is decreasing at a rate of $1~\frac{\text{cm}^3}{\text{min}}$. At what rate is the diameter decreasing when the diameter is $10~\text{cm}$?
I got $1/100 \space (3.14)~\frac{\text{cm}}{\text{min}}$ as my final answer. Please help me!
Thank-you for your time!
