2nd Graph which is selected is correct.

My understanding:
We have 2 curves, to find area I need integral pi(a,b) (outer^2 - inner^2)dx , we also know y=1 is the same as x-axis but rised by 1 SO I should subtract 1 to both equations to bring it back down to origin persay.

Thus I have (1-sqrt x) ^2 - (1-x^2)^2 == answer

^ answer wrong, do not understand where I went wrong
