Homework Statement
Use the shell method to find the volume of the area enclosed by:
[itex]y= 16-x^2[/itex] , [itex]y= 16[/itex],[itex]x=4[/itex], around [itex]y=16[/itex]
Homework Equations
[tex]2\pi\int (shell height)( shell radius)[/tex]
The Attempt at a Solution
I tried using the disk method and obtained [tex]\frac{1024}{5}*\pi[/tex]
but I'm having trouble because they as to specifically use the shell method and so far I think the [tex]shell height = 5 - \sqrt{25-y}[/tex] , but I have no idea how to get the radius, and is the integration on y=0 to y=25?
EDIT: Nevermind, I found the answer
