Provide an appropriate response.The region shown here is to be revolved about the x-axis to generate a solid. Which of the methods (disk, washer, shell) could you use to find the volume of the solid? How many integrals would be required in each case?
What will be an ideal response?
The volume can be found using the shell method with 1 integral. Since x = 2y - y2 cannot be solved for y, the washer method cannot be used.
