Calculate it with Euler's relation:
Faces + vertices = edges + 2
A sphere has an infinite number of faces - so it has an infinite number of edges.

There is different information about spheres in our old math book and our new one. Addison-Wesley Mathematics , 1987, shows: A sphere has Zero flat faces, Zero vertices's, Zero straight edges, Zero curved edges and ONE curved face. Harcourt Brace Jovanovich Mathematics Plus ,1992, shows the same information except it says zero curved faces. Is one right and the other wrong or has someone made a change?

It is round, so a sphere doesn't really have a face or edge.

A hollow sphere will have two surfaces....one inner and one outer.
A solid sphere will have one surface; a true sphere would have no edges.

How many faces does a cylinder have? How many faces does a sphere

It has exactly three times the amount of edges as it does corners.
