Sphere Volume Calculation Formula
The formula for calculating the volume of a sphere is:
V = 4/3 * π * r³
where V is the volume and r is the radius of the sphere.
Sphere Volume Categories and Interpretation
| Range (cubic inches) | Interpretation |
|---|---|
| 0 – 10 | Tiny sphere |
| 10 – 50 | Small sphere |
| 50 – 100 | Medium sphere |
| 100 – 500 | Large sphere |
| 500+ | Gigantic sphere |
Sphere Volume Calculation Examples
| Individual | Sphere radius (inches) | Volume (cubic inches) | Calculation |
