Q6. Let D be the (bounded) region in the first quadrant of the plane z = 0 (i.e. the quadrant given by x 2 0, y 2 0) bounded by the curves r = 0, y = 2vr and x + y = 3. (a) Sketch the region D. 2 marks (b) Use a double integral to find the volume of the solid T below the surface z = 2ry and above the region D.
