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 two curved edges, which are the edges where the curved surface meets the two circular bases. In addition to these curved edges, a cylinder also has two flat circular faces but no sharp edges.
A circular-based pyramid has a total of two types of edges: the circular edge of the base and the edges connecting the apex to each point on the base. The base itself has one circular edge, and if the base is divided into ( n ) equal segments, there will be ( n ) edges connecting the apex to each of these segments. Therefore, the total number of edges is ( n + 1 ), where ( n ) is the number of segments that the circular base is divided into.
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.
