A bicone is the tegum product of a circle and a digon. It is also the result of attaching two cones at their bases.
Equations
- Variables:
r ⇒ radius of base of bicone
h ⇒ perpendicular height of bicone from the circle to one of the vertices
- The hypervolumes of a cone are given by:
total edge length = 2πr
surface area = 2πr√(r2 + h2))
volume = 2π∕3 · r2h
- The planar cross-sections (n) of a cone are:
[!x,!y] ⇒ rhombus
[!z] ⇒ circle
