So I did this method that might work, but it didn’t. What did I do wrong this time?

I think the reason you got it wrong is that in the third step, after integrating, you put y twice in the function

the integral should just be

#

2pi * 9 *y

#

after evaluating

Oh yeah I got that one wrong. But I was able to fix it, thanks!
