(i) Given:

Diameter of the spherical ball (d)= 28 cm

Radius =d/2= 28/2 cm = 14 cm

Amount of water displaced by a solid spherical ball = Volume of spherical ball = 4/3πr³

= (4/3 × 22/7 × 14 × 14 × 14)
= 34496/3 = 11498.67 cm³

Amount of water displaced by a solid spherical ball= 11498.67 cm³

(ii) Diameter of the spherical ball (d)= 0.21 m
Radius (r) = d/2= 0.21/2 m = 0.105 m

Amount of water displaced by a solid spherical ball = Volume of spherical ball= 4/3πr³

=(4/3×22/7×0.105×0.105×0.105)

= 0.004851 m³

Amount of water displaced by a solid spherical ball =0.004851 m³
