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;

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.

Hi lakeheadca;

I do look pretty good with wikipedia behind me.

I think they involve Numerical Approximation and differentiation.

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.
