How to Calculate Sphere Volume and Surface Area

Formula

The volume of a sphere is V = (4/3) x pi x r³ and its surface area is SA = 4 x pi x r².

These formulas are fundamental in physics, engineering, and everyday calculations.

Common use cases:

  • Ball and balloon volume estimation
  • Planet and star size calculations
  • Tank capacity for spherical vessels
