decreasing at the rate of 1 cm/ sec, while its volume is decreasing at the rate of 271' cm3 / sec.
(It retains its cylindrical shape while all this is happening.) If, at a given instant, its volume
is 2411' cm3 and its height is 6 cm, determine whether its radius is increasing or decreasing
at that instant, and at what rate. 7. (15 points) Determine the maximum and minimum values of the function f (w) = a: — 33:
