Diameter of a Sphere, Given Its Volume

Diameter of a Sphere, Given Its Volume

Would any one know how to calculate the diameter of a sphere, given its volume?

For instance, if you had a sphere containing 5000ccs of water, how could you figure out what its diameter is?

Thanks,
Cris Helmare

You'd use this formula here:

diameter = 2 * (volume * 3/4 * 1/Pi)[sup]1/3[/sup]

In your case, a (full) sphere with a volume of 5000 cubic centimeters has a diameter of 21.215688 centimeters.

Thanks very much, unfortunately, I'm not used to raising anything to a fractional power.

I can multiply my volume by three-quarters and divide that by pi.  But I get stuck at that point and can't duplicate your result.

Nevermind.

Cubed root...  Got it.

Thanks again!
