Total. _____(100) NAME (print): 1) Consider the bounded domain D in the ﬁrst quadrant of the my plane
between the curves y = 3:3 and y = 231/3. (a) Calculate the area of D. [10 points] (b) If the domain D corresponds to a slab (lamina) with variable density
p(:c, y) = my, what is the mass of the slab and what are the coordinates of
its center of mass? [10 points] NAME (print): 2) (a) Sketch the region of integration and evaluate the integral. [10 points]
