A solid sphere of radius r is melted and recast into the shape of a solid cylinder of heighty ‘r’. Then the radius of base of solid cylinder will be.............

Explanation

To find the radius of the base of the solid cylinder formed by melting a solid sphere of radius \( r \), we can follow these steps:

### Step 1: Calculate the volume of the sphere
The formula for the volume \( V \) of a sphere with radius \( r \) is given by:

\[ V = \frac{4}{3} \pi r^3 \]
