About this calculator
This calculator computes a sphere's volume (4/3 × π × r³) and surface area (4 × π × r²) from its radius, the two measurements that describe how much space a sphere takes up and how much material it would take to cover it.
It's used in physics and engineering problems involving balls, tanks, and spherical containers — estimating how much liquid or gas a spherical tank holds, or how much paint or coating covers a spherical surface — as well as in geometry classes teaching 3D solids. It also comes up in real-world estimation, like comparing the volume of two differently sized balls or planets.
