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.
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
There is no such shape.
