How to Calculate Sphere Volume
The volume of a sphere measures the three-dimensional space it occupies. Used in physics, engineering, and for calculating tank/ball volumes.
Sphere Volume Formula
V = (4/3) × π × r³
Where:
- V = Volume
- π = Pi (3.14159)
- r = Radius
Step-by-Step:
- 1
Cube the radius
Calculate r³ = r × r × r.
- 2
Multiply by 4π/3
V = 4/3 × π × r³.
Worked Examples:
Basketball
r: 12 cm
Result: 7,238 cm³
V = 4/3 × π × 12³ = 7,238.23 cm³
