Need help with an area question!

OpenStudy (dls):

Using integration find the area of that part of circle x^2+y^2=16, which is exterior to the parabola y^2=6x

OpenStudy (dls):

I want to know where am I wrong if i do it like this.. 4pi is the area for1 quadrant.so Required area, \[\LARGE 4\pi + 4\pi + 2 \int\limits_0^\sqrt{12}\frac{y^2}{6}dy\]

xdy means bounded with y axis right?so..

ganeshie8 (ganeshie8):

your integral gives u area under parabola. thats not the entire area

i would instead calculate the white area and subtract it from the area of the circle. because you need to add one more integral for the area above the parabola
