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? x = - y2 
What will be an ideal response?
The volume can be found using the washer method with 2 integrals or using the shell method with 1 integral.
