When transporting milk, large cylindrical carrying tanks on semi trucks are used. Let's say that a truck has a maximum capacity 01'2023 cubic feet (approximately 15,000 gallons)of milk. The height and radius are measured in feet. FH.3. (a) (10 points) What radius of the tank will minimize the material used? ROUND YOUR FINAL ANSWER TO THE NEAREST WHOLE NUMBER. (b) (10 points) For the same tank used in problem 6, when the truck gets to the farmer, the tank is tilted upright, and milk flows out of the tank at 20 cubic feet per minute, keeping a roughly cylindrical shape. The radius of the milk level is your answer to part a. If you could not solve part a, user = 5. At what rate does the height of milk change during the draining process? d h Milk goes out
