A Cylinder
One curved surface (that goes round the cylinder) and 2 flat ends
If you consider a cylinder, it has two faces, of you consider a cone instead, it has one face ONLY.
It is one of the flat circular bit, and is at the end of the cylinder.
A Semi-Sphere :)
A cylinder. Technically, the curved surface of a cylinder is not called a face, only the flat surfaces, so a cylinder has 2 faces and one curved surface.

Only one. All squares are figures drawn entirely on a flat surface.
A cylinder has 2 flat surfaces and 1 curved surface.In differential geometry, a cylinder is defined more broadly as any ruled surface spanned by a one-parameter family of parallel lines. As such it can have any number of flat surfaces but need not have any at all. A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinderrespectively; these have no flat surfaces.
If you consider a cylinder, it has two faces, of you consider a cone instead, it has one face ONLY.
A cylinder has two faces. An object is considered to have a face when one of the sides is flat. For example, a cube has 6 face because it has 6 areas on its surface that are flat.
It is one of the flat circular bit, and is at the end of the cylinder.
One flat surface is a table. Many flat surfaces are facets.
They are alike because they are both 3 dimensional. They are different because the cube has 6 flat faces, but the cylinder has only 2 flat faces and one curved face.
