WebFirst we must take into account the following in order to calculate the area, volume and radius of the regular polyhedrons: A = A = area. V = V = volume. a = a = edge. R = R = radius of the circumscribed sphere. r = r = radius of the inscribed sphere. \rho = ρ = radius of the sphere tangent to the edges. WebA regular polyhedron is a polyhedron whose symmetry group acts transitively on its flags. A regular polyhedron is highly symmetrical, ... This simply reflects that the surface is a topological 2-sphere, and so is also true, for example, of any polyhedron which is star-shaped with respect to some interior point. philly meatballs
