hi
http://www.calcchat.com/book/Calculus-ETF-5e/
part b they want you to rotate it about the y-axis and in part c about the line x = 3.
I don't understand this difference in writing for part b... 3^2 - (y^2)^2
And in part c they write (3-y)^2 I don't get it.
It is chapter 7 section 2 question 11.
Thanks
