Problem
A vertical cylindrical water tank of internal radius 2 m becomes full to the brim after a solid metal cylinder of the same radius and height 1.5 m is gently lowered so that it rests flat on the bottom. The total volume of water in the tank after lowering the metal block is 30m3. Calculate the height of water in the tank before the block was lowered. (Take π=722.)
