1) A cylindrical tank with a radius of 10 feet and a height of 20 feet is leaking. An observer notices that the height of the tank is goinf down at a constant rate of 1 foot per second. At what rate is the water leaking our of the rank (measured in volume) when the height of the water is 5 feet? The colume of a cylinder of height h and radius is V=pi*r2*h.

a. -314

b. - 1,245

c. - 1,570

d. - 100

e. None of these

2) What are the units for the previous problem

Raccoon City monitors the height of the water in its cylindrical water tank with an automatic recording device. The tank has a radius of 20 feet. Water is constantly pumped into the tank at a rate of 2400 cubic feet per hour. If the water level was 16.05 feet at 6:59 am and 15.95 feet at 7:01 am, estimate the rate at which the residents of Raccoon City were using water at 7:00 am. Round to the nearest cubic foot...

A paper cup in the shape of a cone with height 5 cm and radius 3 cm with the point of the cone at the bottom. A small leak develops in the cup causing water to leak out at a rate of 0.1 cm3/s. Find the rate at which the height of the water in the cup changes when the depth of the water is 2 cm. Recall that the volume of a cone is v=1/3(pi)(r2)h

Suppose water is leaking from a tank through a circular hole of area Ah at its bottom. When water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cAh 2gh , where c (0 < c < 1) is an empirical constant. A tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its...

A student fills a tank of radius .15m with water to a height of .5m and pokes a small, 1.0 cm diameter hole at a distance 0.03m from the bottom of the tank. The water flows out of the small hole into an empty, 0.2 m diameter container placed below the tank.  The student uses a garden hose to keep the water level in the tank at the original height. What is the velocity of the water as it leaves the...
