Write a Python function that gets the radius $r,$ the $R$ value, and the $H$ value and returns the volume of

material in the silo. You need to use an if statement to calculate the volume of material.

$ifdR$ You need the volume $of$ conical part only

$ifd>R$ You need the full volume $of$ conical part

$+$ the volume $of$ cylinderical part

Call the function in the script for the following cases and print the results:

$H=11\mathrm{.}2m$

$H=4m$

For both cases, $r=5m$ and $R=5m.$
