Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis.
y=9x^2, x=1, y=0, about the x-axis
I know that 9x^2 is a parabola but what exactly am I supposed to do here? Am I trying to find the volume of what is on the right had side of the graph if I drew a vertical line at x=1 (kind of looks like a butterfly wing)?
Before anyone says to read the book, I did. This is an online calculus class and the professor refuses to answer questions from the students, he claims it is not his job to answer questions, just present the information and grade the tests.
Any help would be greatly appreciated.
