2. A rectangular lot is bounded on one side by a concrete wall. The owner wishes to put up fences on the 3 remaining sides. Give the length and the width of the largest lot that can be enclosed if the length of the available fencing material is 800 ft. 3. Sand is being sifted onto a conical pile at the rate of 0.3 ft3 /sec. It was also observed that at any instance, the base diameter of the pile is twice that of the height. How fast is the height of the pile increasing when the pile is 2 ft high?
