Curved surfaces, such as those found in cylinders, cones, and spheres, are not classified as ‘faces’. Similarly, flat surfaces with curved boundaries, such as the circular surfaces of cylinders and cones, are not ‘faces’.

Students should realize that a cone has only one face, and you need more than one face to form an edge. Ask: Does a cone have any vertices? Lead students to see that a cone has no edges, but the point where the surface of the cone ends is called the vertex of the cone. Say: Look at the cylinder.

Beside this, Does a cone have a face or base?

A cone has two faces; one curved surface and the circular face as a base.

Likewise,Â What type of face does a cone have?

Students should realize that a cone has only one face, and you need more than one face to form an edge. Ask: Does a cone have any vertices? Lead students to see that a cone has no edges, but the point where the surface of the cone ends is called the vertex of the cone. Say: Look at the cylinder.

Also,Â Does a circle have a flat face?

The flat surfaces of a solid figure are its faces, or sides as they are commonly called. … Because a circle is a flat, plane shape, it is a face. But because it is round around the outside, it does not form any edges or vertices. A cylinder has two circular faces but also no edges or vertices.
