A balloon, which always remains spherical, has a variable radius. Find the rate at which its volume is increasing when the radius when the later is 10 cm

Explanation

To solve the problem, we need to find the rate at which the volume of a spherical balloon is increasing when the radius is 10 cm.

### Step-by-Step Solution:

1. **Understand the Volume of a Sphere**:
The formula for the volume \( V \) of a sphere with radius \( r \) is given by:
\[
V = \frac{4}{3} \pi r^3
