Answer:
Cylinder
A cylinder is a closed solid shape with two parallel bases generally circular in shape connected by two parallel sides. A cylinder may also be defined as a rectangle with circular bases. These circular bases are always parallel and congruent to one another. A cylinder when unrolled gives a flattened look of a rectangle. Base and sides together form a cylinder. The line joining the two circular bases at the center is the axis of the cylinder.
