A cylinder (round can) has a circular base and a circular top with vertical sides in between. Let r be the radius of the top of the can and let I; be the height. The surface area of the cylinder, A, is A 2 Zara-2 + 2117'}; (Mo circles, one for the top and one for the bottom plus a rolled up rectangle for the sides). r_= radius ._- ..'. .' Area = h(2:n:r} \"1' i H C) "I. Circumference 2m Part 3: Assume that the height of your cylinder is 6 inches. Consider A as a function of r, so we can write that as A (r) = 2 m2 + 12 rrr. What is the domain of A (r)? In other words, for which values of r is A (1') dened
