Answer:
(i) Radius of sphere, r = 7 cm
Using, Volume of sphere = (4/3) πr3
= (4/3)×(22/7)×73
= 4312/3
Hence, volume of the sphere is 4312/3 cm3
(ii) Radius of sphere, r = 0.63 m
Using, volume of sphere = (4/3) πr3
= (4/3)×(22/7)×0.633
= 1.0478
Hence, volume of the sphere is 1.05 m3 (approx
Step-by-step explanation:
