Step-by-step explanation:
Since one of the boundaries is y = 0, we need to find the roots of the function . Using the quadratic equation, we get
But since the region is also bounded by , that means that our limits of integration are from
(instead of -3) to
.
Now let's find the volume using the cylindrical shells method. The volume of rotation of the region is given by
Answer:
