first of all I think it's called a CYLINDER and since the sides are round the on the cylinder it has no verticies(right angles).
Cylinda is, if we may remark, very nicely shaped, with no vertices or edges.Unfortunately, however, she has been accused of having several faces.
A pentacontagon has 50 vertices (not vertices's!).
