The parabola $y^2=4x$ divides the area of the circle $x^2+y^2=5$ in two parts. The area of the smaller part is equal to:
A
$\frac{1}{3} + 5sin^{-1} (\frac{2}{\sqrt5})$
B
$\frac{2}{3} + \sqrt5sin^{-1} (\frac{2}{\sqrt5})$
C
$\frac{2}{3} + 5sin^{-1} (\frac{2}{\sqrt5})$
D
$\frac{1}{3} + \sqrt5sin^{-1} (\frac{2}{\sqrt5})$
