Homework Statement
Use cylindrical coordinates to evaluate the triple integral
[tex]\int[/tex][tex]\int[/tex][tex]\int[/tex] [tex]\sqrt{x^2+y^2}[/tex] dV in region E
where E is the solid bounded by the circular paraboloid z=9-(x^2+y^2) and the xy-plane.
Homework Equations
knowing that x = rcos[tex]\theta[/tex]
y= rsin[tex]\theta[/tex]
z=z
for a coordinates in clindrical
The Attempt at a Solution
I'm not sure how to get the bounds of integration for this problem. I know it has something to do with the paraboloid given but I am not very good at drawing such a figure. I do understand that you need to change the x and y into xcos and ysin in order to integral the problem. any help would be greatly appreciated!
