Step-by-step explanation:
![\frac{2 + 20}{2} \\ \\ \frac{22}{2 } = 11](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%20%2B%2020%7D%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cfrac%7B22%7D%7B2%20%7D%20%20%3D%2011)
Step-by-step explanation:
The volume of a cylinder is given by :
![V=\pi r^2 h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2%20h)
r is the radius of the base of a cylinder
h is height of cylinder
The height of a cylinder is twice the radius of its base. It means that h = 2r
So, volume of cylinder becomes :
![V=\pi r^2(2r)\\\\V=2\pi r^3](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2%282r%29%5C%5C%5C%5CV%3D2%5Cpi%20r%5E3)
So, the volume of the cylinder is given by the expression
