Yes, a cylinder has both curved and flat surface. Considering a solid cylinder standing on its end, the circular base and the circular top are flat surfaces. The surface connecting the top and bottom is curved.

A cone.
A sphere that has been sliced by a plane will have a circular base and a curved surface. In the special case that this plane goes through the centre of the sphere, the shape will be a hemisphere. in simple terms it would actually be a cone...
