A cylinder has two circular bases.

Which shape has exactly two circular bases?

Cylinder. A cylinder is a solid shape defined on a three-dimensional plane. It holds two parallel bases, circular in shape, joined by a curved surface(like a tube), at a fixed distance. It has a flat base and a flat top.

What are circular bases?

The top and bottom of a cylinder are two congruent circles, called bases. The height h of a cylinder is the perpendicular distance between these bases, and the radius r of a cylinder is simply the radius of the circular bases.
