Find the area ofthe region enclosed by the curves x + y2 = D and x + 53/2 = 16. The area of the region enclosed by the curves is . (Simplify your answer.) Find the area of the "triangular" region in the first quadrant, bounded on the left by the y-axis and on the right by the curves y= 4 sin (2x) and y =4 cos (2x). The area of the bound, "trianguiar" region is . (Type an exact answer, using radicals as needed.) Which of the following integrals, if either, calculates the area of the shaded region shown to the right? Give reasons for your answer. l 1 a. I(x(x))dx= IZde 1 1 Choose the correct answer below. Choose the correct answer below. 0 A. The integral in part b calculates the area of the shaded region because function y = - x is above the function y= x. C) B. The integral in part a calculates the area of the shaded region because function y = x is above the function y = - x. C) C. Neither, because the graph of y = x is above the graph of y = x for x 0
