Answer :
The volume of the sphere = 4851 cm3
Let the radius of the sphere = r
As,
Volume of the sphere = 4851 cm3
⇒ 4/3πr3 = 4851
⇒ r3 = 92618
⇒ r = 3√92618
⇒ r = 212cm
Now,
The Curved surface area of the sphere = 4πr2
= 4 × 22/7 × 21/2 × 21/2
= 1386 cm2
So,
The curved surface area of the sphere is 1386 cm2
