A shot-put is a metallic sphere of radius 4.9 cm. If the density of the metal is 7.8 g per cm 3 , find the mass of the shot-put.

Volume of sphere = Putting values in equation we get, Since, the density of the metal is 7.8 g per cm 3 . Mass = Volume × Density. So, the mass of the metallic sphere 493 × 7.8 = 3845441.6 g = = 3.845 kg. Hence, the mass of the metallic sphere is approx 3.85 kg.
