Given sphereRadius, compute the volume of a sphere and assign sphereVolume with the result. Use $(4\mathrm{.}0/3\mathrm{.}0)$ to perform floating$-$

point division, instead of $(4/3)$ which performs integer division.

Volume of sphere $=(\frac{4\mathrm{.}0}{3\mathrm{.}0})r^3($Hint: $r^3$ can be computed using $*.$ Use the constant Math.PI for the value of pi$.)$
