When you say "What face" did you mean "What solid" has one curved face and two other flat faces? A solid that can be imagined is a melon wedge, cut from a sphere. Two flat faces come from the two cuts with a knife, and the one curved face that formed the rind. If you did not mean "What solid" then that makes your question unclear. I cannot imagine a face made from three other faces. Perhaps a face made from three other lines with one of them curved? It would seem you used a word wrong somewhere in your original question.

A cylinder.
The shape described has two flat faces, one curved face, and two edges. It could be a cylinder or a cone with a circular base.
A cylinder or a frustrum of a cone.
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.
