A water treatment plant uses a large cylindrical storage tank to collect treated water before distribution. The tank has a diameter of 20 meters. During the filling process, water flows into the tank at a constant rate of 314 cubic meters per hour. To monitor the process, an engineer records the rate of change of the depth of water in the tank. Find the value that the engineer recorded.
