    Volume of Hemisphere=(4/6) Pi r^3 Thus, (4/6)*Pi*2^3=(16/3)*Pi

    yes, volume of the whole sphere is 4/3 pi r ^3. so volume of half the sphere is half of 4/3pi r^3

    man, you just need to relax, everything is better than you could possibly imagine :) so, just go outside, chill a bit, ride a bike or something. You could also go horseriding. So mate, nothing to worry about, forget your homework. School is just there to confuse you. :)
