Yes, the top and the bottom.

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.
There are 2 flat surfaces, both are circles.
2 flat surfaces unless it is rolled up in which case it has 2 curved surfaces.
a plane
The top and bottom flat surfaces (the 2 circles or ellipses) and the curved surface make up the 3 surfaces.
Flat surfaces?... Well, a cone has a circle on the bottom (as its base) and, when rolled out, a rectangle for its side that the apex is part of at the top. So I'd say the answer to your question is "2," if I have a correct understanding your question. ~OneAndOnly13
