How many edges does a cylinder have?
A cylinder has two edges. This however is applicable only if the edge is defined in terms of plane geometry as ‘Ëœa boundary of a plane geometric figure’â„¢. In terms of polyhedra, where an edge is ‘Ëœa straight line that is the intersection of two faces of a solid figure’â„¢, a cylinder has no edge. This is according to the University of Drexel’â„¢s the Math Forum
