Etymology

From cylindrus from κύλινδρος.

Pronunciation

Noun

  1. 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.
  2. A solid figure bounded by a cylinder and two parallel planes intersecting the cylinder.
  3. Any object in the form of a circular cylinder.
    • 1898 — H. G. Wells, The War of the Worlds Ch.4
      A big greyish rounded bulk, the size, perhaps, of a bear, was rising slowly and painfully out of the cylinder.
  4. A cylindrical cavity or chamber in a mechanism, such as the counterpart to a piston found in a piston-driven engine.
  5. A container in the form of a cylinder with rounded ends for storing pressurized gas.
  6. An early form of phonograph recording, made on a wax cylinder.
