Calculate the volume of a sphere using its radius.
Enter the radius to calculate the volume of a sphere.
The volume of a sphere is calculated using the formula:
\[ V = \frac{4}{3} \pi r^3 \]
Where:
For example, if \( r = 3 \) units, then \( V = \frac{4}{3} \pi \times 3^3 = \frac{4}{3} \pi \times 27 = 36\pi \approx 113.10 \) cubic units.
