Frustum of cone is the part of cone when it is cut by a plane into two parts. The upper part of cone remains same in shape but the bottom part makes a frustum.
The conical frustum formula of cone in terms of radius ‘r’ and height ‘h’ is given by;
Slant height = √((r – r’)² + h²)
Volume = (1/3) x π x h x (r² + r’² + (r x r’))

Volume of a conical frustum =V=(1/3)*pi*h*(r12+r22+(r1*r2))
