I have the equation ... Determine the volume for ; 0<x<3 (greater than or equal to on the <, I didn't know how to do that); 0<y<3 (also greater than or equal to)

Hello, Wouldn't it be ?

Be careful of that z limit. It wouldn't be 2Pi, unless you're using polar. Perhaps try this: A double integral may be better:
I'm not used to it, can a volume be obtained with a double integral ?
Fornuately, for me the professor gave us a solution set a.) 62 b.) 63 c.) 64 d.) None of these so if I'm in the ballpark, I'll know it. I might just try both

Yes, double integrals give volume. Look at choice b
Oh yeah indeed... I really have to learn my lessons Thanks !
