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.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

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

Re: Find Sphere Volume
!!!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.

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.
