A cylindrical can of radius 5cm and height 12 cm is leaking water at a rate of 4 cm 3 (cubed) per minute. How fast is the height of the water changing when the water level is 3 cm from the bottom of the can.(this is a,,related rates,, problem. Volume of a cylinder is given by V=pie r2(squared)h.) 8048

A conical container open to the top is being filled at the rate of 10 ft3/min.The container is 20 feet high with a radius of 6 feet at the top.How rapidly is height of the fluid increasing when the height is 10 feet?

Hint;1; Express the cone,s liquid volume in terms of r and h. Then express r in terms of h using the given dimensions of the cone.That allows you to express the liquid volume in cone as a function of just h, the height of the liquid.

Hint;2;Keep n,in your expressions until the very end-tider. 8046

We have a right triangle with one leg growing and one shrinking.By how much is the hypotenuse growing(or shrinking0 if x is increasing at 6 ft/sec and  y is decreasing at 3 ft/sec when x= 60 ft and y=80 ft?Be sure to indicate if the hypotenuse is growing or shrinking.Be careful with the signs of the derivatives.Yes,you must first find the hypotenuse. 8043
