15. A paper cup has the shape of a cone with height 12 cm and radius 8 cm (at the top). If water is poured into the cup at a rate of 3 cm s. how fast is the water level rising when the water is 9 cm deep?
A water tank has the shape of an inverted cone of height 6 m with a circular base of radius 2 m. If water is being pumped into the tank at 3 m?/min, how fast is the water level rising when the water is 4 m deep. Round your answer to two decimal places. The water level is rising at a rate of Number Units The area of a square is increasing at a rate of 28 centimeters squared per...
2) Water is poured into a conical container at the rate of 5 cm/sec. The cone points directly down, and it has a height of 15 cm and a base radius of 5 cm. How fast is the water level rising when the water is 2 cm deep (at its deepest point)?

A cone-shaped tank with the tip down has a radius of 10 ?? and a height of 20 ??. We lead water into the tank at an inflow rate of 1 liter per minute. Calculate the growth rate of the area of the water surface when the water depth is 8 dm.
7. (30 pts) An open cut uranium mine is excavated in the shape of an inverted frustrum of a right circular cone (ignoring the berms). See the figure below. The volume of this shape is equal to 2 The slope of the pit is 1 (45°). At ground level the radius of the cut is 120 m. At a depth of 15 m, a vein of uranium ore starts. The average ore density is 3.2 g/cm3. Excavation of the uranium...

8 An inverted conical tank has height 4 m and radius 1 m at the top. When the d oil flows in at the rate 2 m/min. How fast is the level rising? 9 A 6-ft man walks away from a 15-ft lamp post. When he is 21 ft from the post.
A particular cylindrical bucket has a height of 50.0 cm, and the radius of its circular cross-section is 15 cm. The bucket is empty, aside from containing air. The bucket is then inverted so that its open end is down and, being careful not to lose any of the air trapped inside, the bucket is lowered below the surface of a fresh-water lake so the water-air interface in the bucket is 40.0 m below the surface of the lake. To...
Suppose that a tank containing a certain liquid has an outlet near the bottom. Let h(t) denote the height of the liquid's surface above the outlet. Torricelli's principle states that the outflow velocity v at the outlet is equal to the velocity of a particle falling freely (with no drag) from the height h (a) Show that v2gh, where g is the acceleration due to gravity. (b) By equating the rate of outflow to the rate of change of liquid...
(20%) Problem 3: A nozzle with a radius of 0.16 cm is attached to a garden hose with a radius of 0.91 cm that is pointed straight up. The flow rate through hose and nozzle is 0.55 L/s. Randomized Variables n = 0.16 cm rn=0.91 cm Q=0.55 L/S 50% Part (a) Calculate the maximum height to which water could be squirted with the hose if it emerges from the nozzle in m. ha = 238.75 h2 = 238.8 Correct! >...
