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= ?

a)50

b)100

c)200

d)300

e)400

small tank volume: pi*(r/2)^2*h

big tank volume: pi*r^2*h

factor small volume out =

pi*(r^2/4)*h

since big volume is 4 times as the small one, it's 300% more.

(4 is 3 more than 1).
