Volume of a sphere = (4/3)πr³

Volume of a cylinder = πr²h

Let the radius of the cylinder be r cm.

Given, sphere of radius 5 cm is immersed in water filled in a cylinder, the level of water rises cm

Volume of the sphere = Volume of the water in the cylinder.

⇒ ×5³ = π × r² ×

⇒ r² = 4×5²

⇒ r = 10 cm
