1. The problem statement, all variables and given/known data
A frustum is cut from height h parallel toits base and distant 2/3h
Show that position of center of gravity of frustum is independent of the semi-vertical angle of cone(i) alpha and (ii)find its distance from base


2. Relevant equations
Given the CG of the cone is 1/4 its height from the plane face


3. The attempt at a solution
