You can put this solution on YOUR website! Use integration method to find the volume generated by two curves, and ,turning 360 degrees, setting x-axis as the pivot.
--------------------
-----------
You can see in the graph that the 2 curves are symmetrical about x = 1, and about the x-axis.
----
--> find the volume of the left half rotated about the x-axis.
----------- from 0 to 1:
Using disks centered on the x-axis:
Vol = pi*r^2*dx
--> Vol = 2pi per half
Total volume = 4pi cubic units.
