GEOMETRY: CIRCLE & SPHERE

This calculator will work out the radius of a circle, the diameter of a circle, the area of a circle, the area of a sphere and the volume of a sphere from any of those values. For example, if you know the surface area of a sphere you can calculate all the other values. The formulas are all written next to the value boxes. It is fun to calculate from different starting points.
CIRCLE & SPHERE CALCULATOR simply enter the desired value in any of the right hand boxes and click the corresponding button to calculate all other values. For example if you know the radius enter the value in the top right box and click the top left button. If you know the volume of the sphere enter it into the bottom right hand box and click the calculate button at bottom left: RADIUS = (r) = enter a value for DIAMETER & click to DIAMETER = (2 r)= enter a value for CIRCUMFERENCE & click to CIRCUMFERENCE = (2 π r) = enter a value for CIRCLE AREA & click to CIRCLE AREA = (π r2) = enter a value for SPHERE SURFACE AREA & click to SPHERE SURFACE AREA = (4 π r2) = enter a value for SPHERE VOLUME & click to SPHERE VOLUME = (4/3 π r3) =
