A sphere has just one curved face.
2 plane faces, 1 curved face
Get a ball. Draw any closed shape on it. The part inside the curve that you drew is one curved face and that is contained by the surface of the ball which is the other curved face.
A cone. It has a circle for the base, and a curved face tapering to a point.
2. One at the top and one at the bottom. The face that is cylindrical cannot be counted as a base because it is curved - in 3D shapes the base must be flat.
