How it works
A sphere is a three-dimensional shape where every point on the surface is the same distance from the center.
- Volume: 4/3 × π × r³
- Surface area: 4 × π × r²
- Diameter: 2r
Examples
- r = 1 → volume = 4.18879...
- r = 3 → volume and surface area of a larger sphere
- r = 10 → geometry scaling example

FAQ
- What does this sphere volume calculator compute?
It computes sphere volume, surface area, and diameter from the radius.
- What formula is used for sphere volume?
The formula is V = 4/3 × π × r³.
- What formula is used for sphere surface area?
The formula is A = 4 × π × r².
- Can radius be 0 or negative?
No. Radius must be greater than 0 for a meaningful geometric sphere.
