Bicone
A bicone or dicone (bi- comes from Latin, di- from Greek) 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 base-to-base.
A bicone has circular symmetry and orthogonal bilateral symmetry.
Geometry
For a circular bicone with radius R and height center-to-top H, the formula for volume becomes
For a right circular cone, the surface area is
- where is the slant height.
Related polyhedra
A bicone can be seen as a polyhedral limiting case of an n-gonal bipyramid where n approaches infinity. It can also be seen as a dual of a cylinder as an infinite-side prism.[1]

gollark: Pointers are admittedly a bit hard to explain beyond stuff like "pointers are things which point to other things".
gollark: Pointers are discomplicateful.
gollark: Pointers are just monoids in the category of endofunctors.
gollark: I don't understand why people don't understand them.
gollark: It doesn't even have an interesting chemical structure.
