A solid cylinder has three plane surfaces: two circular bases at the top and bottom, and one curved lateral surface that wraps around the sides. The curved surface is not a plane surface, while the two bases are. Thus, there are two plane surfaces in a solid cylinder.
A cylinder has 2 opposite parallel flat surfaces.
A solid hemisphere has two surfaces: one curved surface and one flat circular base. The curved surface is the outer part of the hemisphere, while the flat base is the circular section that sits on a plane.
A cylinder has three faces and two round surfaces.
There are 2 flat surfaces, both are circles.
Sphere, ellipsoid, torus, paraboloid, hyperboloid are shapes with only curved surfaces. Hemisphere, quadrant, cone and cylinder are examples of shapes with curved and plane surfaces. There are, of course, many others.
