A spherical ball of lead 3cm in diameter is melted and recast into three spherical balls. If the diameters of two balls be `3/2c m` and 2cm, find the diameter of the third ball.

Explanation

To find the diameter of the third spherical ball, we can follow these steps:

### Step 1: Calculate the radius of the original ball
The diameter of the original ball is given as 3 cm. The radius (R) is half of the diameter.

\[ R = \frac{3 \text{ cm}}{2} = 1.5 \text{ cm} \]
