Volume of Cylinder
Theorem
By Height and Cross-Sectional Area
Let $\CC$ be a cylinder such that:
- the cross-sections of $\CC$ at right angles to the generatrices of $\CC$ have area $A$
- the height of $\CC$ is $h$
- the inclination of the generatrices of $\CC$ to the base of $\CC$ is $\theta$.
The volume $\VV$ of $\CC$ is given by the formula:
- $\VV = \dfrac {A h} {\sin \theta} = A h \csc \theta$
By Slant Height and Cross-Sectional Area
Let $\CC$ be a cylinder such that:
- the cross-sections of $\CC$ at right angles to the generatrices of $\CC$ have area $A$
- the slant height of $\CC$ is $l$
The volume $\VV$ of $\CC$ is given by the formula:
- $\VV = A l$
By Height and Base Area
Let $\CC$ be a cylinder such that:
- the bases of $\CC$ have area $A$
- the height of $\CC$ is $h$.
The volume $\VV$ of $\CC$ is given by the formula:
- $\VV = A h$
By Slant Height and Base Area
Let $\CC$ be a cylinder such that:
- the bases of $\CC$ have area $A$
- the slant height of $\CC$ is $l$
- the inclination of the generatrices of $\CC$ to the base of $\CC$ is $\theta$.
The volume $\VV$ of $\CC$ is given by the formula:
- $\VV = A l \sin \theta$
