# Cylinder vs. Prism

## Difference Between Cylinder and Prism

#### Cylindernoun

(geometry) A surface created by projecting a closed two-dimensional curve along an axis intersecting the plane of the curve.

*When the two-dimensional curve is a circle, the cylinder is called a circular cylinder. When the axis is perpendicular to the plane of the curve, the cylinder is called a right cylinder. In non-mathematical usage, both right and circular are usually implied.*

#### Prismnoun

(geometry) A polyhedron with parallel ends of the same size and shape, the other faces being parallelogram-shaped sides.

#### Cylindernoun

(geometry) A solid figure bounded by a cylinder and two parallel planes intersecting the cylinder.

#### Prismnoun

A transparent block in the shape of a prism (typically with triangular ends), used to split or reflect light.

#### Cylindernoun

Any object in the form of a circular cylinder.

#### Prismnoun

A crystal in which the faces are parallel to the vertical axis.

#### Cylindernoun

A cylindrical cavity or chamber in a mechanism, such as the counterpart to a piston found in a piston-driven engine.

#### Prismnoun

a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms

#### Cylindernoun

(automotive) The space in which a piston travels inside a reciprocating engine or pump.

#### Prismnoun

optical device having a triangular shape and made of glass or quartz; used to deviate a beam or invert an image

#### Cylindernoun

A container in the form of a cylinder with rounded ends for storing pressurized gas; a gas cylinder.

#### Cylindernoun

An early form of phonograph recording, made on a wax cylinder.

#### Cylindernoun

The part of a revolver that contains chambers for the cartridges.

#### Cylindernoun

(computing) The corresponding tracks on a vertical arrangement of disks in a disk drive considered as a unit of data capacity.

#### Cylinderverb

(transitive) To calender; to press (paper, etc.) between rollers to make it glossy.

#### Cylindernoun

a cylindrical container for oxygen or compressed air

#### Cylindernoun

a solid bounded by a cylindrical surface and two parallel planes (the bases)

#### Cylindernoun

a surface generated by rotating a parallel line around a fixed line

#### Cylindernoun

a chamber within which piston moves
