Find the volume of a sphere whose radius is :
(i) 2 cm
(ii) 3.5 cm
(iii) 10.5 cm
Volume of a sphere = (4/3)πr3
(i) radius is 2 cm
⇒ Volume of the sphere = (4/3) × (22/7) × 23 = 33.52 cm3
(ii) radius is 3.5 cm
⇒ Volume of the sphere = (4/3) × (22/7) × 3.53 = 179.67 cm3
(iii) radius is 10.5 cm
⇒ Volume of the sphere = (4/3) × (22/7) × (10.5)3 = 4851 cm3
