8-95.

**Multiple Choice:**The function*f*(*x*) =*x*^{2}is bounded by the*y*-axis and the line*y*= 4. The volume generated by revolving the region about the*y*-axis can be found by which of the following integrals? Homework Help ✎a. I only

b. II only

c. III only

d. I and II

e. I and III

If you want to use disks/washers, then rotate horizontal rectangles...

that means that both the bounds and the integrand must be written in terms of *y*.

If you want to use shells, then use *x*-values.
