파이널 테스트에 점수로 들어가는 부분이라서 부탁드릴께요..
제가 문제는 다 풀었구여.. 맞는지만 좀 확인해주십사 해서요..
간절히 부탁드려요..
1) a cylindrical can is to be designed and constructed to hold 0.75 liters . it costs 0.75 cents per square centimeter to
build the top of the can, 0.50 cents per square centimeter to build the bottom of the can, and 0.30 cents per square
centimeter to construct the side of the can. find the dimensions of the can which minimize the cost of constructing
the can. ( approximate r=3.86 centimeters, h=16.02 centimeters)
2) a liquid is being pumped into a cylindrical tank with a radius of 3 feet. when the depth of the liquid is 4 feet'
the depth of the liquid is increasing at a rate of 0.2 feet per second. find the rate at which the volume of the liquid i
is changing at that instant. (5.65 cubic feet per second)
감사드립니다..
