Zero, there are NO edges on a cylinder, according to mathematical definitions (the answer is not two).

It is 2

A cylinder has 2 edges

It does have two!

No edges!

It has 2 edges. 1 at the top and another edge at the bottom. It's only my guess..

It depends on how you define "edge". Some teachers define it as a straight line, so cylinders have no edges.

But if "edge" is defined as "a boundary between smooth surfaces" then a cylinder has 2 edges.
