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:

$\VV = A l \sin \theta$
