Volume of a solid
I need help with this one, I had a graph of the equation through derive at school, but now that I'm at home I can no longer access that program (the free trial also expired on me). I can't seem to get it to graph on my Ti-89; it gives me an error. Anyways, here is the given problem:
First use Derive to graph the equation (x-40)y^2=10x(x-30). Now find the volume of the solid obtained by revolving the region between the graph and the x-axis for 0<x<30* around the x-axis. Show all work.
*Those <'s are suppose to be less then or equal to.
Could someone give me some help? A step by step would be awesome since I have a test coming up soon, but I'd appreciate anything!
Does this help?
