In mathematics, a cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases are normally circular in shape (like a circle) and the center of the two bases are joined by a line segment, which is called the axis.
A cylinder is a 3D solid shape that consists of two identical and parallel bases linked by a curved surface. These bases are like circular disks. The line passing from the center or joining the centers of two circular bases is called the axis of the cylinder shape.
A cylinder (from Ancient Greek κύλινδρος (kúlindros) 'roller, tumbler') [1] has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. In elementary geometry, it is considered a prism with a circle as its base.
A cylinder is one of the most basic curved three dimensional geometric shapes, with the surface formed by the points at a fixed distance from a given line segment, known as the axis of the cylinder. The shape can be thought of as a circular prism. Both the surface and the solid shape created inside can be called a cylinder.

A cylinder is a closed solid that has two parallel (usually circular) bases connected by a curved surface. It can be a right cylinder or an oblique cylinder.

A cylinder is made up of two congruent, parallel bases, that are usually circles, and a curved lateral surface that meets the bases at their perimeters (circumferences for circular cylinders). The height, h, of a cylinder is the length of a line segment perpendicular to the bases.
6 days ago · In its most general usage, the word "cylinder" refers to a solid bounded by a closed generalized cylinder (a.k.a. cylindrical surface) and two parallel planes (Kern and Bland 1948, p. 32; Harris and Stocker 1998, p. 102). A cylinder of this sort having a polygonal base is therefore a prism (Zwillinger 1995, p. 308).
What is a cylinder? A cylinder is a three dimensional shape, or 3D shape. It has two ends that are both circles of the same size. It has one curved side that goes all the way around. Properties of a cylinder. A cylinder, like all 3D shapes, can be identified by its properties – the number of faces, edges, and vertices. Face: a flat surface.
