No. Can they be rounded? Yes.
A cylinder has 2 circular edges that are parallel to each other at its bases
Two circular edges
A cylinder has 3 faces: two circular bases and one curved surface. It has 2 vertices located at the top and bottom circular edges, and it has an infinite number of edges along the curved surface where the circular bases meet. However, if considering just the circular edges, it has 2 edges.
A cylinder has a circular face at each end, and a rectangular face folder around the middle. The only edges are the edges of the circular ends.
One circular edge.
Both.
A cone has one circular face. It only has one vertice and it does not have any edges since the face is circular.
Faces: 2 circular, 1 curved rectangular. Vertices (not vertexes!): None Edges: 2 circular.
A cylinder has no vertices (not vertexes!) It has 2 circular edges.
A rod is an elongated cylinder, so it has 2 circular edges.
It has 3 faces, 2 circular edges and no vertices
It has one circular edge.
