Volume of Circular Cylinder/Height
Theorem
Let $\CC$ be a circular cylinder such that:
- the bases of $\CC$ are circles of radius $r$
- the height of $\CC$ is $h$.
The volume $\VV$ of $\CC$ is given by the formula:
- $\VV = \pi r^2 h$
Proof
From Volume of Cylinder in terms of Height and Base Area:
- $\VV = \AA h$
where $\AA$ is the area of the base of $\CC$.
From Area of Circle:
- $\AA = \pi r^2$
The result follows.
