Calculus 3 - Double Integrals

I have this Calc 3 problem that I want to check to see if I solved it right. I put the problem into a word document then took pictures to try to best show what I did. Let me know if I made any mistakes or if you have any comments! Thank you.

Looks ok to me but the integrals are not too difficult and you could solve it exactly.
