x 19 3. Evaluate SSR x2+yz dA, where R is the annular region bounded by x2 + y2 = 9 and x2 + y = 16 by switching to polar coordinates. Include a sketch of R with all pertinent information labeled and evaluate the polar integral symbolically, show every step. Final answer should be an exact number, no decimals. x 19 3.
