Question

shell method, revolve y=x+2, y=x^2 about the y axis

Answer 1

If something is revolving what kind of shape does it have?

Answer 2

It can have a shape of a cylinder or cone so in this case you would want to set up an integral in cylindrical coordinate

Answer 3

scratch the cylindrical coordinates. You are setting up a single integral. The boundaries of the integral are going to be the points where the functions intersect and the lowest point of y=x+ 2
then what you want to integrate is 2 * pi * r * h dx where r is the radius and h is the height.

Answer 4

I really dislike doing single integrals for volume so if you can set up a triple integral then do it.

Answer 5

its a single integral problem
