A & B please, step by step. I have no idea how to do these!!

Problem 2: [15 pts] The region R is bounded by r = y" - 4 and y = 2 -r, which intersect at (0, 2) and (5, -3). Additional Directions: You must label the images below with any necessary quantities. This includes any quantities in area formulas, outer and inner radius for washer method, and shell radius and height for shell method. Failure to label the images will result in no credit for your revisions. A. [5 pts] Suppose that R is the base of a solid. Cross-sections taken parallel to the r-axis are squares. Set up, but do not evaluate, an integral or sum of integrals that would give the volume of the solid if evaluated. ( Make sure to include a solution, a reflection, and an reference to an example of a similar problem from elsewhere in the course) B. [5 pts] Suppose that R is revolved about the line y = 5. Use the washer method to set up an integral or sum of integrals that would give the volume of the solid if evaluated. Do not evaluate your integral(s). ( Make sure to include a solution, a reflection, and an reference to an example of a similar problem from elsewhere in the course)
