Conenoun

(geometry) A surface of revolution formed by rotating a segment of a line around another line that intersects the first line.

Cylindernoun

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

āWhen 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.ā;

Cone

A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex. A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the apex, to all of the points on a base that is in a plane that does not contain the apex.
