Use differentials to estimate the amount of metal in a closed cylindrical can that is 30 cm high and 6 cm in diameter if the metal in the top and the bottom is 0.2 cm thick and the metal in the sides is 0.05 cm thick. (Round your answer to two decimal places.)
Answers: 3
and the differential dh is approximated to 
. We can see the increment of radius is the thick of the metal in the sides, and the increment of the height is the thick of the metal in the top and bottom. Thus dr=0.05 cm, dr=0.2 cm
