(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Use shell method to find the volume.

y = 3 - (x^2 / 3) where (x > 0)

x = 0

y = 3/2

roated around x = 3

2. Relevant equations

2Pi * Integration of (radius)*(length * width) = Volume

3. The attempt at a solution

Radius: (x - 3)

Height: Function

Width: Delta X

This is how I see the image.

2 * Pi Integrationg from 0 to 3 [ (x-3)*(3 - (x^2/3)) ]dx - 2 * Pi * Integration from ? to ? volume of the top piece

I'm not sure how to get the top piece :(.
