Sphere Volume Calculator
Calculate sphere volume, surface area, diameter, great circle circumference, and radius from radius, diameter, volume, surface area, or circumference.
Sphere volume from radius or diameter
English search intent separates sphere volume from spherical cap and surface-area-only pages. This calculator keeps the complete sphere model and supports radius, diameter, volume, surface area, and great circle circumference inputs.
r is the sphere radius.
S is the surface area of the sphere.
