# Total Area of a Frustum of a Right Circular Cone

## Description

In geometry, a frustum is the portion of a solid (normally a cone or pyramid) that lies between two parallel planes cutting it.The total area of a frustum of a Right Circular Cone can be calculated by the radius of the lower base, the radius of the upper base, the height and the slant height of the frustum.
