A circular prism, or a cylinder, has 2 edges and no vertices.
It has 3 faces, 2 circular edges and no vertices
It has 3 faces, 2 circular edges and no vertices
It has 3 faces, 2 circular edges and no vertices
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 8 edges
No but it does have a pair of circular parallel edges.
A cylinder has no vertices (not vertexes!) It has 2 circular edges.
It depends on the configuration. Here are some: A nonagon-based pyramid will have 18 edges and 10 vertices; An octagon based prism will have 24 edges and 16 vertices; A pentagon-based dipyramid will have 15 edges and 7 vertices. There are others.
A triangular based pyramid has 6 edges and 4 vertices.
A triangular based prism has 6 vertices and 9 edges.
A square based pyramid has 8 edges and 5 vertices.
