A sphere is continuous with no edges, so a "face" doesn't really apply. It has a surface, and if you consider that a "face" then it has one. If you are looking inside and out, then two. If you do not consider a surface a...

Date: 12/28/2003 at 17:21:33 From: Cara Subject: Characteristics of polyhedra I need to know how many faces, vertices, and edges do cylinders, cones, and spheres have? Logically I would say that a sphere has 1 face, 0 vertices and 0 edges.

Question: How many faces are there on a sphere? ... You CAN of course, draw some additional curved 'edges' on the sphere, and have more faces (each additional edge either adds on more vertex or one more face - provided the edges and vertices are connected into a single piece).

Incidence Relations on a Sphere ... Then we will use Girard's Theorem to prove Euler's Theorem that says that in any convex, three dimensional polyhedron we have V - E + F = 2, where V is the number of vertices, E is the number of edges, and F is the number of faces.

Zero IF you are using terms used for polyhedra - which are often the general terms shown in primary school maths text books 1) if you want to clarify by stating it is a CURVED face.

A vertex can either be the intersection of polygon edges, or a local extremum. A sphere has none of the former type, but an infinite number of the latter type. Everywhere on a sphere, the derivative of curvature is zero, for a sphere has co...
