How many curved faces does a cone have?

A cone has a singular curved face. Cones consist of two main parts: a circular base and a curved top that spans from the outside of the base to a single point at the top.

There are two main components of a cone that are important for describing the shape of a cone. The base is always a circle, but its size will depend on its radius. The second main part is the height of the apex, which is the distance from the base to the top point of the cone. A large base with a small apex height will have sides that are much less steep than a small base with a high apex.
