integration - Area for an ellipsoid

"Calculate the area for the rotation ellipsoid you get by rotating the ellipsoid x22+y2=1 around the x-axis."



I solved for x:



y=±1x22



Then did y=0 to get the integration limits, ±(2).




So I've ended up with an integral I don't know if it's correct, and even if it is, I can't solve it.



4π221x221x21x22dx
