A water tank has the shape of an inverted circular cone (point down) with a base of radius 6 feet and a depth of 8 feet. Suppose that water is being pumped into the tank at a constant rate of 4 cubic feet per minute. Find the rate at which the water level is rising when the water in the tank is 3 feet deep. When the water in the tank is 3 feet deep, what is the radius of the tank at that height? Use your formula that relates the variables, their rates of change, and the given rate of change to determine the rate at which the height of the water is changing when the water is 3 ft deep.

Question
A water tank has the shape of an inverted circular cone
(point down) with a base of radius 6 feet and a depth of
8 feet. Suppose that water is being pumped into the
tank at a constant rate of 4 cubic feet per minute. Find
the rate at which the water level is rising when the
water in the tank is 3 feet deep.
When the water in the tank is 3 feet deep, what is the
radius of the tank at that height?
Use your formula that relates the variables, their rates
of change, and the given rate of change to determine
the rate at which the height of the water is changing
when the water is 3 ft deep.
