Hi Harsh
Surface Area of Sphere = 5544
4πr2 = 5544
πr2 = 5544/4
πr2 = 1386
(22/7)r2 = 1386
r2 = 1386 × (7/22)
r2 = (1386/22) × 7
r2 = 63 × 7
r2 = 9 × 7 × 7
r2 = 9 × 72
r2 = 32 × 72
r2 = (3 × 7)2
r2 = 212
r = 21 cm
Now,
Volume of Sphere = 4/3πr3
Volume of Sphere = 4/3 × (22/7) × (21)3
Volume of Sphere = 38803 cm3
