The amount of water displaced by a solid spherical ball when it is completely immersed in water is equal to its volume. Volume of a sphere of radius r is 43pir^3 As the diameter of the ball is 4.2 cm, its radius r = 2.1 cmHence, volume of water displaced = 43pir^3 = 43 × 227 × 2.1 × 2.1 × 2.1 = 38.808 cm ^3

Answer:
6703 litres
Step-by-step explanation:
Diameter = 42cm
Lateral surface = 69
42x69 = 2898litres
Cornell surface = 3805litres
2898litres + 3805litrws
= 6703 litres
