(4 points) The figure below open cylindrical can, S, standing on the xyplane. (S has a bottom and sides, but no top.) The side of S is given by x2 + y2 = 16, and its height is 5. (3) Give a parametric equation, ?(t) for the rim, C. 7(1) = 555 , with 555 S t S 555 (For this problem, enter your vector equation with angle-bracket notation: .) (b) If S is oriented outward and downward, find f9 curl (3y_i. + 3x; + 321:) - d2. [S cur1(3y-i)+ 3x]- + 32%) - d3 = 555
