👉 In mathematics, a cone is a solid geometric shape with two parallel circular bases and one vertex. It is often used in geometry to represent three-dimensional space. A cone can be defined as follows: 1. A cone is a closed surface that results from rotating an elliptical base about its major axis. 2. The radius of the base (r) is the distance between the two points where the circular bases meet, and it measures perpendicular to the plane containing both bases. 3. The slant
