Basic Spherical Properties Calculator



Enter any ONE of the four spherical variables (R, C, A or V) and this program will compute the other three unknown variables.  The linear units can be interpreted as anything, such as meters, inches, miles, feet, etc., whatever you decide the units represent.

 R = Radius    unit(s)
 C = Circumference    unit(s)
 A = Area of Surface    square unit(s)
 V = Volume    cubic unit(s)
   

    Enter only ONE known variable and leave all the others blank.
    Those unknown variables will be computed and displayed here.
The Basic Formulas Applied

Let:
R = Radius of Sphere
C = Circumference
A = Area of Surface
V = Volume
