"A cylindrical tank is buried beneath a lake in order to safely store radioactive waste. Inside the tank is a measuring rod that identifies the level of radioactive waste.
Determine the points on the measuring rod that would identify when the tank is 1/4 , 1/2 and 3/4 full.
Assume the diameter of the cylinder is 1m and the cylinder is 5m long.
