Exercise 7 Construct a right circular cone with the base in xy-plane. Center of the base is (15,10,0), radius of the base is 6, and the height of the cone is 17. Construct a right circular cylinder for which the points (15,0,6),(15,20,6) are the center of its bases, and the radius is 4. Using Boolean operations construct the union, difference and intersection of those solids.
