closed cylindrical tank contains 36pi cubic feet of water and its filled to half its capacity. When the tank is placed upright on its circular base
on level ground, the height of water in the tank is 4 feet. When the tank is placed on its side on level ground, w hat is the height, in feet, of the
surface of the water above the ground? Choose the correct choice.
A) 1 ft  B) 2 ft  C) 3 ft  D) 4 ft  E) 5 ft
We know that the volume of cylinder = πr^2h   Given tank height = 4ft.   ⇒ π r^2 4 = 36π   ⇒ r = 3   So the radius is 3 which means the diameter is 6.   As the cylinder is filled to initially exactly half of the capacity, When this cylinder is placed on its side, Water comes up to the height of the radius.   So water comes up to 3 ft   ANSWER:3 ft
