4.2 Related Rates (#differentiation) Solve the following problems using the related
rates method. (Adapted from Stewart)
(a) A spherical iron ball 6 cm in diameter is coated with a layer of ice with uniform
thickness. If the ice melts at a rate of 25 cm³/min how fast is the thickness of
the ice decreasing when it is 4 cm thick?
4
(b) The altitude of an isosceles triangle is decreasing at a rate of 3 cm/min while
its perimeter is increasing at a rate of 2 cm/min. How fast is each of the sides
changing when the sides are a = 4 cm, b = 4 cm, and c = 6 cm?
