13. Find the volume of the beaker

A 22 $cm$ tall beaker is in the form of a cylinder surmounted on a frustum. The base radius of the cylinder is 2.2 $cm$ and the height of the frustum is $6.6$ $cm$. If the base of the beaker has a  radius which is twice that of its rim, then find the volume of the beaker.

 

Answer:

 

The volume of the beaker $=$  $cm^3$
