A full stationary oil tank that is a right circular cylinder has a radius of 100 feet and a height of 25 feet. Oil is pumped from the stationary tank to an oil truck that has a tank that is a right circular cylinder until the truck's tank is completely filled. If the truck's tank has a radius of 6 feet and a height of 10 feet, how far (in feet) did the oil level drop in the stationary tank? Choose the most appropriate option:
A) 0.036 B) 0.36 C) 0.6 D) 6 E) 3.6
The volume of oil pumped to the tank = The volume of oil taken away from stationary cylinder.   pi*36*10 = pi*h*100*100 (h is distance that the oil level dropped)   h = 360/10,000 = 36/1000=
