A cone has one circular base and a vertex that is not on the base.as described on math.com
If you mean "How many diagonals can be drawn from one vertex of a figure with 16 sides", the formula is n-3, where "n" being the number of sides of the figure. So 16-3 = 13 diagonals that can be drawn from one vertex.

true
vertex
A spitial figure with a circular bases no edges and one vertex
Because the base of a cone is round, it is the only three dimensional figure with only one vertex.

This figure is a CONE.

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.
