A certain barrel, which is a right circular cylinder, is filled to capacity with 200 gallons of oil. The first barrel is poured into a second barrel, also a right circular cylinder, which is empty. The second barrel is twice as tall as the first barrel and has twice the diameter of the first barrel. If all of the oil in the first barrel is poured into the second barrel, how much empty capacity, in gallons, is left in the second barrel? Choose the correct choice from the following.
A) There is no empty capacity B) 1100 gallons C) 1300 gallons D) 1400 gallons E) 1800 gallons
Radius of first cylinder=r, diameter=2r, height=h   Radius of second cylinder=2r, diameter=2d and height=2h   Volume of first cylinder=pie (r^2)*h=200   Volume of second cylinder=pie(2r^2)2h   Put the value of pie (r^2)*h=200 in the second cylinder,volume= pie (r^2)*4*2=200*8=
