# Cone

geometric shape
A cone, marked with its height (h) and radius (r)

In common speaking and geometry, a cone is a solid object that one gets when one rotates a right triangle around one of its two short sides, the cone's axis. The disk made by the other short side is called the base, and the point of the axis which is not on the base is the cone's apex or vertex. An object that is shaped like a cone is conical.

The volume ${\displaystyle V}$ of a cone is one third of the product of the area of the base ${\displaystyle A_{B}}$ and the height ${\displaystyle h}$[1]

${\displaystyle V={\frac {1}{3}}A_{B}h.}$
