A sphone is a special case of a pyramid where the base is a sphere. It contains the base sphere and a 3-D surface.
Equations
- Variables:
r ⇒ radius of base of sphone
h ⇒ height of sphone
- All points (x, y, z, w) that lie on the surcell of a sphone will satisfy the following equations:
Unknown
- All points (x, y, z) that lie on the faces of a sphone will satisfy the following equations:
x2 + y2 + z2 = r2
w = 0
- The hypervolumes of a sphone are given by:
total edge length = 0
total surface area = 4π · r2
surcell volume = 4π∕3 · r2 · (r+√(r2+h2)
bulk = π∕3 · r3h
- The realmic cross-sections (n) of a sphone are:
[!x,!y,!z] ⇒ cone
[!w] ⇒ sphere of radius (r − nr∕h)
