Sphere Diameter Calculator
The diameter of a sphere is the maximum straight-line distance through the geometric center. This calculator solves diameter directly using d = 2r, d = ³√(6V / π), or d = √(A / π).
Direct Diameter Formulas
From Radius: d = 2 × r
From Volume: d = ³√[ (6 × V) / π ]
From Surface Area: d = √[ A / π ]
