Each bullet consisted of two parts viz. a cylinder and a hemisphere on one of its base. The total height of bullet is 3.5 cm and radius of base is 2.1 cm. Approximately how many complete bullets can be obtained?
A sphere of diameter 42 cm is melted and bullets are formed from it. The bullet has circular cylindrical shape from one side and conical from other side. The radius of the base of the cylindrical part of the bullet is 6 cm and the cylindrical part has thrice as much length as the conical part. Find how many such bullets can be formed if the curved surface area of the cylindrical part of a bullet is 79.2 cm2.
