### Find Sphere Volume

A sphere is inside a cube. What is volume of sphere?
I don't remember exactly what was the question, perhaps they gave the volume of cube i.e: 100³.
thank you

Hi;

Like that?

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Hi;

If you say that the Volume ot the cube is equal to 100^3 then the sides of the cube are 100. The diameter of the sphere is equal to 100. The volume of the sphere is

V = ( 4 / 3 ) π r^3 = ( 4 / 3 ) π 50^3 = ( 4 / 3 ) *125000 π

!!!Where did you learn this stuff!!!
you guys know almost everything in math.
********** thank you bobby***********
I have two questions which I asked couple of math teachers but couldn't get the answers (even reply:). I know you can solve those problems. I will write and try to ask you later, as soon as my computer work properly. I think they  involve Numerical Approximation and differentiation.

I do look pretty good with wikipedia behind me.

At last, my field! Now you will see me shine! A former boss of mine and one of the smartest people I ever knew said this about my work:

Watching you solve a problem hurts my eyes.

That's not so bad, that could mean anything.
