Answer :

**Given:** Radius of big ball = 3 cm

Radius of first ball = 1.5 cm

Radius of second ball = 2 cm

**To find:** Diameter of the third ball

**Formula Used:**

The volume of the sphere =

**Explanation:**

radius of big ball = 3 cm

So, its volume, v =

The spherical ball of radius 3 cm is melted and recast into three spherical balls.

Let the radius of the third ball be r.

Then, volume of third spherical ball =

Volume of first ball =

Volume of second ball =

The volume of the original spherical ball is equal to that of the total volumes of the three balls.

⇒ r = 2.5 cm

Thus, diameter = 5 cm
