Yes.
An Apex or Vertex of the cone
Double cone is two cones joined at their apex.
You could call the vertex, the apex, the tip, or the point of the cone.
point
The shape of the face on a cone is a circular base at the bottom and a curved surface that narrows smoothly to a point called the apex. This curved surface is referred to as the lateral face of the cone. Overall, a cone has one circular face (the base) and one curved surface.
An Apex or Vertex of the cone
Yes, a cone has an apex. To be precise, it is the point at the tip of the cone. This is also called the vertex of the cone.
A cone does not have a vertex. A vertex is defined as a point where two lines meet; a triangle has three vertices, and the angular face of a pyramid has a vertex. However, a cone is a three-dimensional figure and has a curved surface. The base of a cone is circular. The top of the cone is a single point called the apex of the cone.
Yes, though the proper term is the apex.

point
Infinitely many. There are infinitely many lines from the apex to the base. Every point on each of these lines is on the surface of the cone.
