Explanation Given: ∫ ∫ D x 2 + y 2 d A , where D is the region in the first quadrant bounded by the spiral r = θ , the circle r = 1 and the x -axis. Calculation: The given region is bounded by the polar curves spiral r = θ , the circle r = 1 and the x -axis in first quadrant as shown in the graph: It can be seen from the graph that both the polar curves meet at θ = 1 . Thus, in polar coordinates, the region is defined as: D : 0 ≤ θ ≤ 1 , θ ≤ r ≤ 1 Using polar coordinates to evaluate the integral, ∫ ∫ D x 2 + y 2 d A = ∫ 0 1 ∫ θ 1 ( r ) r d r d θ
