In geometry, a bicone or dicone (from Latin: bi-, and Greek: di-, both meaning "two") is the three-dimensional surface of revolution of a rhombus around one of its axes of symmetry. Equivalently, a bicone is the surface created by joining two congruent right circular cones at their bases. A bicone has circular symmetry and orthogonal bilateral symmetry.

Geometry

For a bicone with radius $r$ and half-height $h$ , the volume is

V={\frac {2}{3}}\pi r^{2}h

and the surface area is

A=2\pi r\ell \,

where

\ell ={\sqrt {r^{2}+h^{2}}}
