Prove that the cylinder inscribed in a right circular cone has maximum curved surface area if the radius of cylinder is half the radius of cone.

Show that the curved surface of a right circualr cylinder inscribed in a right circular cone is maximum when the radius of its base is half that of the cone.

A solid metallic right cone is melted and some solid right circular cylinders are made. If the radius of base of each cylinder is half the radius of cone and the height of each cylinder is one third the height of the cone, then the number of cylinders formed are.
