Frustum of A Right Circular Cone
Frustum of a right circular cone is that portion of right circular cone included between
the base and a section parallel to the base not passing through the vertex.
Lateral Area, AL
The lateral area of the frustum of a right circular cone is equal to one-half the sum of
the circumference of the bases multiplied by slant height. See the derivation of the
formula for lateral area of frustum of a right circular cone.
Volume, V
The volume of a frustum of any cone is equal to one-third of the product of the altitude
and the sum of the upper base, the lower base, and the mean proportional between
the two bases. See the derivation of formula for the volume of any frustum.
