How many vertices and edges does a cone have?

Answer 1

One of each.

Answer 2

Depending on what information and grade level the following would be considered for a three dimensional cone:

If the definition of a face= a flat side

edge= where to faces meet

vertex= where three or more faces meet

then cone would have 1 face (the base), 0 edges, 0 vertices

If the curriculum includes curved surfaces as faces then:

cone would have 2 faces, 1 edge, 0 vertices
