Water is leaking out of an inverted conical tank at a rate of 1.5 cm3 /min at the same time that water is being pumped into the tank at a constant rate. the tank has height 10 cm and the diameter at the top is 6 cm. if the water level is rising at a rate of 1.0 cm/min when the height of the water is 2 cm, find the rate at which water is being pumped into the tank. (a) draw a picture of the situation for any time t. (b) what quantities are given in the problem? what is the unknown quantity you are looking for? (c) write an equation that relates the quantities. (d) finish solving the problem. 3. a police helicopter is flying at 150 mph at a co
