A uniform metallic solid sphere is heated uniformly. Due to thermal expansion, its radius increases at the rate of $0.05 \mathrm{mm} {\left(\mathrm{s}\right)}^{-1}$. Find its rate of change of volume with respect to time when its radius becomes, $10 \mathrm{mm}$. (Take $\mathrm{\pi }=3.14$) $\left(01628{ \mathrm{mm}}^3 {\mathrm{s}}^{-1}\right)$
