Hi,

The volume of a cylinder of radius $r$ cm and height $h$ cm is

\[\pi\;r^2 h \mbox{ cubic cm}\]

and the volume of a cone of radius $r$ cm and height $h$ cm is

\[\frac13 \pi\;r^2 h \mbox{ cubic cm}\]

So the volume of a cone is one-third the volume of a cylinder of the same dimensions.

You can use our volume calculator to find the volume of a cylinder.
