Right Circular Cone

A Right Circular Cone is a three-dimensional solid with a circular base and a single vertex (apex).

It is called right because the axis (height) of the cone is perpendicular to the circular base.

Parts of a Right Circular Cone:

Base – Circular face

Radius (r) – Radius of the base

Height (h) – Distance from the apex to the center of the base

Slant height (l) – Distance from the apex to any point on the boundary of the base

Relation between r, h, and l:

Surface Area Formulae:

Curved Surface Area (CSA) = �

Total Surface Area (TSA) = �
