Dear People, I made a new Mathematical Constant thats called f (pronounced effa) [attachment=0:3sm5cxt0]CodeCogsEqn.gif[/attachment:3sm5cxt0] So, if that is f, then to find the area if a sphere we can just do f(r^3). Finally, 32 digits of f: 4.1887902047863909846168578443727 Thanks, Zach

btw, if anyone could calculate up to 100 digits, please send me them.

Sorry. All I see is f = PI(4/3) What am I missing?

Oh for £^€$@ sake. This "new" constant is four thirds pi???

You Dont Remember the formula 4/3*pi*r^3? F is fricken useful. You don't have to do 4/3*3.14159265(I memorized 100 btw)*(r^3) just do f(r^3) lol...

divide it by f, and then you will get r^3, or r*r*r. [attachment=0:1z1bo0tw]effa2.gif[/attachment:1z1bo0tw] Disregards, Zach

Don't you see that f has really no use? It's like saying I'm making a constant for and for (because a volume of a cone). And why don't make a constant so that you can easily get the volume of a hypersphere? Why don't make a constant for everything ?? Those constants are all useless and so does f. The reason why they made a constant out of pi is because you can't quickly calculate it yourself and because it is needed a lot everywhere. f is only needed for a volume of a sphere...
