I'm 15 and I know the area of a circle=pi r2 and the area of a sphere=3/4 pi r3
I think that volume is wrong. Integrating a r^2 which is present in a circle to get the r^3 in volume would give you a 3 in bottom, not the top.
Hey, what did the engineer say to the tool maker? "Would you like fries with that?" Point in case once again that 99% of engineers are a waste of space... But congrats, you are NOT the 1%. #occupyfuturemcdonaldsenployee
pi (r squared). I leaned that in elementary school
Pi r squared, dumbass!
American education at its finest
?r^2

Pi(r)^2
To smart for the basic stuff!
