Surface area201.0619
Volume268.0826
How this tool works
Diameter d=2r, surface area A=4πr² and volume V=4πr³/3.
Example
A sphere of radius 4 has surface area about 201.062 and volume about 268.083 cubic units.
Common questions
What units are the results?
Diameter uses the radius unit, area uses squared units and volume uses cubic units.
Does this apply to an ellipsoid?
No. A sphere has equal radius in every direction.
