Water is being pumped at a rate of 0.3 cubic meters per minute into a tank that has the shape of an inverted cone. The tank is 5 meters tall and has a diameter at the top of 2 meters. How fast is the water level rising when the depth of the water is 3 meters? Recall that the volume of a cone is onethird the area of the base times the height ( V = 1/3BH)
