Formula
The formula used to calculate sphere volume is:
V = (4/3) · π · r3
Symbols
- V = Sphere volume
- π = Pi = 3.14159…
- r = Sphere radius
Radius of Sphere
Enter the radius of a sphere. The radius is the distance between the centre and any point on the surface of a sphere.
Volume of Sphere
This is the volume contained within a sphere with the specified radius.
