A question about volume (caution: Mathematics and physics question)? Answered
Ok, I know how to figure the "volume of a sphere" and the surface area of said sphere, now I need to know how to figure how much I need to remove from the outside, to reduce the volume by about 1/2.
I suspect this will NOT reduce the size of the entire sphere by 1/2....at least, that doesn't seem logical to me.
Can anyone explain it so that I (not a mathematician) can understand it?
