A.) The dimensions of a box are 10 in, 12 in and 20 in. If the shorter sides are decreasing at a rate of 0.2 in/min and the longest side is increasing at a rate of 0.5 in/min, calculate the rate at which the volume is changing. Give units. Is the volume increasing or decreasing? B.) A solution drains through a conical filter at a rate of 10cc per minute. The height of the funnel is 10cm, and the diameter of the circular opening is 12cm. How fast is the solution level dropping when there is a volume of 15(pi) cc left in the funnel? Give units. (The volume of a cone is V = 1/3(pi)(r^2)(h)
