Definition--3D Geometry Concepts--Cylinder | CylinderTopic3D Geometry DefinitionA cylinder is a three-dimensional geometric figure with two parallel circular bases connected by a curved surface at a fixed distance from each other. DescriptionIn the realm of three-dimensional geometry, a cylinder is a fundamental shape characterized by its two identical, parallel circular bases and a curved surface that connects these bases. The line segment joining the centers of the bases is called the axis of the cylinder, and it is perpendicular to the bases. The distance between the bases is the height of the cylinder, while the radius is the distance from the center to the edge of the base. |
