4. A water tank has the shape of an inverted circular cone with radius 2 ft and depth 8 ft. Water is leaking out of the tank at a rate of 2 ft³/min. Let h represent the depth of water in the tank at any time, t. Compute dh/dt when h = 3 ft. Hint: the volume of a cone is given by V = 1/3 ?r²h.

Step 1
First, we need to find the relationship between the radius (r) and the height (h) of the water in the tank. Since the tank is an inverted cone, we can use similar triangles to find this relationship. Let R be the radius of the tank (2 ft) and H be the depth of Show more…

Functions
A water tank has the shape of an inverted circular cone with base radius 3 m and height 6 m. If water is pumped into the tank at a rate of 4 m^3/min, find the rate at which the water level is rising when the water is 2 m deep. V = 1/3̇πr^2h

Filling a Conical Tank Water is poured into a container in the shape of a right circular cone with radius 4 feet and height 16 feet. See the figure. Express the volume $V$ of the water in the cone as a function of the height $h$ of the water. [Hint: The volume $V$ of a cone of radius $r$ and height $h$ is $V=\frac{1}{3} \pi r^{2} h$.]
