$5\mathrm{.}41$ LAB: Calculate volume of a sphere

Write a function def spherevolume $(r)$ that computes the volume of a sphere with radius $r($volume $=\frac{4}{3^{***}}{}^{***}$ radius ${?}^{{?}^{{?}^{?}}}3).$

Then write a main $()$ function that prompts the user for the value of $r.($This is not the same as if $\_$ name $\_==\text{'}\_$ main $\_\text{'}$ and prints the output formatted so that it contains three decimal places.

Ex$.$ If the input is:

Enter the radius: $3\mathrm{.}8$

then the return value is $($not rounded$)$:

$229\mathrm{.}84729611703878$

but the printed output is:

A sphere has volume: $229\mathrm{.}847$

Please make sure to write the entire program including function def main $()$ : The volume of a sphere is

$\frac{4}{3}{r}^3$
