Two. Considering this is a two-dimensional object, cut out of a piece of paper it would have two flat surfaces, the front and the back. If your talking a about a sphere, the three-dimensional object of a circle, it has no flat surfaces considering it is round.

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
