How do you find the Volume of a Silo?

A silo consists of a cylinder and a hemisphere. So, the volume of the silo is the volume of a cylinder plus the volume of the hemisphere.

Volume of a sphere: 4/3πr3 ---> Hemisphere: 2/3πr3

Volume of a cylinder: πr2h

So, combining the two equations, the full equation to finding the volume of a silo:

V = 2/3πr3 + πr2h
