cyl·in·der (s l  n-dr)n. 1. Mathematics a. The surface generated by a straight line intersecting and moving along a closed plane curve, the directrix, while remaining parallel to a fixed straight line that is not on or parallel to the plane of the directrix. b. The portion of such a surface bounded by two parallel planes and the regions of the planes bounded by the surface. c. A solid bounded by two parallel planes and such a surface, especially such a surface having a circle as its directrix. 2. A cylindrical container or object. 3. Engineering a. The chamber in which a piston of a reciprocating engine moves. b. The chamber of a pump from which fluid is expelled by a piston. 4. The rotating chamber of a revolver that holds the cartridges. 5. Any of several rotating parts in a printing press, especially one that carries the paper. 6. Archaeology A cylindrical stone or clay object with an engraved design or inscription. [Latin cylindrus, from Greek kulindros, from kulindein, to roll.] |   To calculate the volume of a right circular cylinder, multiply the area of the base by the altitude. |

cylindrical adj
| cylinder (sln-dr) A three-dimensional surface or solid object bounded by a curved surface and two parallel circles of equal size at the ends. The curved surface is formed by all the line segments joining corresponding points of the two parallel circles. |  The equation for determining the volume (V) of a cylinder is V =  r2h. |
