(i) Given radius of the sphere, r = 0.63 m
Volume of the sphere, V = (4/3)r3
= (4/3)×(22/7)×0.633
= 1.047 m3
= 1.05 m3 (approx)
Hence the volume of the sphere is 1.05 m3.
(ii) Given radius of the sphere, r = 11.2 cm
Volume of the sphere, V = (4/3)r3
= (4/3)×(22/7)×11.23
= 5887.317 cm3
= 5887.32 cm3 (approx)
Hence the volume of the sphere is 5887.32 cm3.
