¤ Cylinder
EXPLENATION:
- A cylinder has two circular bases and a curved lateral surface.
- A cylinder is like a prism, but the bases of a cylinder are circles instead of polygons.
- Since the surfaces of a cylinder are not polygons (they have round edges and are not always planar figures), we call them surfaces instead of faces.
