A cone is a solid figure formed by
a closed plane curve on a plane (the base, usually a circle) and all the lines
joining points on the base to a fixed point (the vertex) not in the plane of
the base.
For a cone of base radius r and height (or latitude h), the
volume is given by the formula:
An example A cone has a base
radius of 4cm and a height of 5cm, find its volume.
