two cylindrical tanks have the same height, but the radius of one tank equals the diameter of the other. if the volume of the larger is k% more than the volume of the smaller, k= ?
small tank volume: pi*(r/2)^2*h
big tank volume: pi*r^2*h
factor small volume out =
since big volume is 4 times as the small one, it's 300% more.
(4 is 3 more than 1).
