Let  $I$  be the set of points  $(x,y)$  in the Cartesian plane such that   $$ x>\left(\frac{y^4}{9}+2015\right)^{1/4} $$   Let  $f(r)$  denote the area of the intersection of  $I$  and the disk  $x^2+y^2\le r^2$  of radius  $r>0$  centered at the origin  $(0,0)$ . Determine the minimum possible real number  $L$  such that  $f(r)<Lr^2$  for all  $r>0$ .
