The region under the curve y = x2 - a between x = 1 and x = 3 is revolved about the line x = 3. Using the cylindrical shell method, the radius of the element is O 3 -X O X O x2 - x O x - 3 Question 44 2 pts The area of the region bounded by the curve y = V2 - a and the lines y = -x and the x-axis is O 10/3 O 12 O 2/3 0 4
