Find the area of the region in the first quadrant enclosed by x-axis, line `x=sqrt(3)y`and the circle `x^2+y^2=4`.

Explanation

The given area of the region bounded by the circles, `x^{2}+y^{2}=4, x=sqrt{3} y, `and the x-axis is the area O A B.

The standard form of cirlce is given by,


`{x}^{2}+{y}^{2}={a}^{2}`


by comparing we have now ,


a=2
