When you horizontally cut a cylinder, you will see a circle as the resulting 2D shape. This circle is formed by the intersection of the plane (the cut) with the curved surface of the cylinder. The circle will have the same diameter as the base of the cylinder.
A cylinder is a 3d shape because you can see the in side of it.
A pentagon is a 2-D shape. There is a 3-D shape with 12 faces, each a regular pentagon. It's called a dodecahedron. To make one out of (stiff) paper, you would cut out a "net", then fold and glue the edges. See related link for an illustration of a net you could print out.
No, but it looks like it. Actually the leter S does have a line of symmetry. Not vertically but horizontally. See, S.
Yes. The cylinder is a solid (solid object), and it has two faces that are circles, and will roll - just as described in the question. Use the link below to see a diagram of a cylinder.
