Sphere and ball
Circumference, surface area and Volume of Sphere
The best calculator for the sphere you’ve ever seen :-)
Calculation
Enter a value to any field - the others are calculated themselves. If you change a value in any field, the others are automatically recalculated.
For decimals you can enter either points or commas
as decimal marks (but only one decimal point in a value).
The result will be in the units that you enter into the fields.
For example: if you enter kilometres, calculation will be also in kilometres.
If appears an error NaN, check whether you enter to the field
a correct value, ie. without any letters and other characters.
Formula
d = | 2 × r | [m] | |
O = | π × d = 2 × π × r | [m] | |
P = | π × d² = 4 × π × r² | [m²] | |
V = | 1/6 π × d³ = 4/3 π × r³ | [m³] |

d … diameter = 2 × radius
r … radius = ½ of diameter
S … center of sphere
o … axis
π (Pi) = 3,14 (about)
Sphere and Cube
