  1. cylinder

    A cylinder is a three-dimensional geometric shape that consists of two parallel circular bases that are congruent (same size and shape) and one curved surface connecting the bases. The bases are always at equal distance from each other and the axis, which is the segment connecting the centers of both bases, is perpendicular to them. It is commonly seen in everyday objects such as cans, tubes, or barrels.

  1. Cylinder

    A cylinder is one of the most basic curvilinear geometric shapes, the surface formed by the points at a fixed distance from a given line segment, the axis of the cylinder. The solid enclosed by this surface and by two planes perpendicular to the axis is also called a cylinder. The surface area and the volume of a cylinder have been known since deep antiquity. In differential geometry, a cylinder is defined more broadly as any ruled surface spanned by a one-parameter family of parallel lines. A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinder respectively. The open cylinder is topologically equivalent to both the open annulus and the punctured plane.
