- A cone is 24 cm high and 15.75 cm in radius. If it is melted and recast into smaller cones, each is 5.25 cm in diameter and 6 cm high, how many such cones can be made?
- The radius and height of a right circular cone are 9 cm and 36 cm respectively. Another cone is 54 cm high and the diameter of the base is 24 cm. Both the cones are melted together and recast into a cylinder whose base radius is 9 cm. Find the height of cylinder.
- A cylinder is 12 cm high and the radius of its base is 6 cm. Another cylinder is 18 cm high and the radius of the base is 8 cm. Both the cylinder are melted together and recast into a right circular cone with height 33 cm. Find the diameter of the base of the cone.
