i) Draw the frustum of a cone. How it is different from a truncated cone?
Ans: A cone cut by a plane parallel to the base removing the apex is called frustum of the cone. whereas when it is cut by any other plane then it is called the truncated cone. Thus the frustum of the cone is a special case of the truncated cone.
