Area under the curve

Find the area bounded by the curves √5â‰¤|z|â‰¤2√3 and z²+z²-2zz+8z+8z>0

I have solved it up to tracing the graph,After that,I don't know how to proceed,Please solve that part alone!!!!

R=2âˆš3
r=âˆš5

so area= 1/2 (Î R² - Î r²)

the second curve is a parabola.. there is a small issue in it! :)

arey bhaiya! i din see the minus sign :( so my x were getting cancelled :(

A1 = area between big circle and parabola
A2= area btween small ciecle and parabola.

reqd. area = A1- A2

i tihnk, taking a horizontal dy strip will be more helpful than dx..
