The volume of a sphere is 4851 cm³. Find its curved surface area.

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
