Which solid has a curved surface and two congruent circular bases?

Explanation:
A cylinder is the solid with a curved surface and two congruent circular bases. Think of a can or a drum: it has two ends that are circles of the same size, and the side around them is curved. That combination—curved outer surface plus two equal circular bases—fits the description exactly. A sphere is all curved with no bases, a cone has a curved surface but only one base, and a cube has flat faces with no curved surface. So the shape that matches is the cylinder.
