## mathstina 3 years ago Evaluate the integral ∭(xz+3z)dV,where E is the region bounded by the cylinder x^2 +z^2 = 9 and the planes x+y=3,z=0 and y=0 above the xy-plane.

Im just donig these myself so I dont know how much help I can be, but the tricky part is setting up the limits in the correct order. I think the first limit is x + y = 3 so it would be -3 to 3 for the first one (I think)

2. mathstina

is it z-simple?

3. mathstina

hw?

4. experimentX

could you start by drawing picture?

5. mathstina

thats e part i confused abt. the region ...

6. mathstina

any help

|dw:1353429578503:dw| this is your last plane ... show how is the region gonna look like?

10. mathstina

ok. hw to find the limits?

11. experimentX

lol ... first of all picture your region ... then you will find the limits.

13. mathstina

ok. then... i m nt strong in this chpt.

14. experimentX

first you need to visualize ... then approach the problem. |dw:1353430430927:dw|

15. mathstina

ok

ok so far i unerstand. thanks . i need ur continual assistance; steps to e solution. i need to sign out. cya.

if possible only could write the steps of the integration and the final ans.
