Surface area and volume

Surface areas and volumes in one shot

A rocket is in the form of a right circular cylinder closed at the lower end and surmounted by a cone with the same radius as that of the cylinder. The diamter and height of the cylinder are 6 cm and 12 cm , respectively. If the slant height of the conical portion is 5 cm, the find the total surface area and volume of the rocket. ( use pi = 3.14 ).
