A truncated cone (frustum) is the portion of a cone that lies between the base and a plane parallel to the base.

The lateral surface area of a truncated cone is calculated by the formula:

S_{l a t e r a l} = π (R + r) l

The total surface area of a truncated cone is calculated as the sum of the lateral surface area and the areas of the two bases:

S_{t o t a l} = π (R + r) l + π R^{2} + π r^{2}
