CONE AND FRUCT CONE: SECTIONS OF A CONE WITH A PLANE AND THE SURFACE OF A CONE

Abstract

A cone is a geometric body in space, consisting of a circular base and one vertex. All lines connected from the points at the base of the cone to the vertex form a cone. The radius of the base of the cone is r, and the height is h. The lateral surface, the full surface, the volume of the cone, and the geometric shapes formed when cut by various planes are widely studied in geometry.
