PLEASE SOMEBODY HELP ME 14. A conical water tank has a radius of 10 ft and is 24 ft high. If water flows out of the tank at a rate of 20 ft'/Imin, how fast is the depth of the water decreasing when the water is 16 ft deep? 15. Air is being pumped into a spherical balloon at a rate of 20 in'/min. How fast is the radius of the balloon increasing when the radius is 6 in? 16. Water is being withdrawn from a conical reservoir 3 ft in radius and 10 ft deep at a rate of 4 ft/min. How fast is the surface falling when the depth of the water is 6 ft? How fast is the area of the surface decreasing at this moment? 17. Oil spilled from a ruptured tanker spreads out in a circle whose area increases at a constant rate of 6 mi2 lhr. How fast is the radius of the spill increasing when the area is 9 mi2? 18. Water is leaking out of a cylindrical cup with a radius of 4 cm. If the water is leaking at a rate of 3.5 cm3 per second, then the level of the water is dropping at what rate?
