a cone
A conic section.
a pyramid
Yes, the point on the cone is a vertex.Typical math textbooks define a cone as "A solid figure with one circular face and one vertex." So yes, there is one vertex.
Pyramid
any face that is not a base is?
A cone+++The original answer also had "Cube", which is obviously wrong!
A spitial figure with a circular bases no edges and one vertex
a square* * * * *A square does not have only 1 vertex: it has 4.The correct answer is an infinite cone.
Because the base of a cone is round, it is the only three dimensional figure with only one vertex.
There is no such shape.
it is a three dimensional cone , the circle is the edge of the figure and the curved side is the body of the cone, the vertex is the point of the cone
