The question is read as follows: Solid lies between planes perpendicular to the x-axis at x=1 and x=-1 . The cross sections are perpendicular to the x-axis are circular disk.s whose diamters run from the parabola y=x^2 to the parabola y=2-x^2 FInd the volume of the solid.

I tried doing this by the given integral - v= int (a to b) A(x) dx =int (a to b) pi R(x)^2 dx

I ve determined that the radius should equal to 2 . I dont know where to go from here to determine the limits of integration (a and b values) and such. Any help is appreciated
