How many faces vertices and edges does a cyilder have?

Answer 1

I can't speak with any authority, BUT seems to me a cylinder can exist in one of three configurations which would effect the answer (a fixed length with two discrete ends--like a line segment, an infinite length with one fixed end--like a ray, and an infinite length with neither end fixed--like a line).

Hence a cylinder has two faces (inside and outside), either zero vertices (if the tube is zero-ended) or infinite vertices (at infinitesimal degrees of rotation around the bends of the tube at the defined end or ends of the tube) (if the tube is single or double ended), and infinite edges (running longitudinally the length of the tube if there is one or two ends).

I'm totally guessing as the the number of edges in the case of a zero ended cylinder, but I would have to say infinite there as well, and relying on a series of radially discrete but longitudinally non-discrete albeit perhaps imaginary point around the cylinder in the two extreme lengthwise directions of the cylinder.
