Consider the solid obtained by rotating the region bounded by the given curves about the x-axis. Find the volume V of this solid.Sketch the region, the solid, and a typical disk or washer.( if you can not sketh it, that is not a big problem for me)
y= (1/10)x^2 , y= (11/10)-x^2


my answer is (506 pi /375)

my answer is (506 pi /375)<<< How did you get it ? - show work.
 
Here's a graph of your region rotated about the x-axis.

Your solution is correct. Good work.
