The shape is called sector. The formal mathematical definition of sector is the portion of a circle bounded by two radii and the included arc.

A prism has no curved surfaces. It has 5 or more flat faces.
When a curved surface is represented on a flat surface, usually either distances or directions must be distorted. Various "projections" exist to minimize these distortions in whatever way is important to the cartographer.

A prism has no curved surfaces. It has 5 or more flat faces.
The shape that has two faces and can roll is a cylinder. A cylinder has two circular faces at either end, and its curved surface allows it to roll smoothly. This shape is commonly seen in everyday objects such as cans, coins, and wheels.
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.
