Area of the region in which point `p(x,y),{x>0}` lies; such that `y<=sqrt(16-x^(2))` and `|tan^(-1)((y)/(x))|<=(pi)/(3)` is

Let P(x,y) be a moving point in the x-y plane such that [x].[y] = 2, where [.] denotes the greatest inte- ger function, then area of the region containing the points P(x,y) is equal to :

Area of the region which consists of all the points satisfying the conditions |x-y|+|x+y| =2, is equal to

The area of the region containing the points (x, y) satisfy-ing 4<=x^(2)+y^(2)<=2(|x|+|y|) is

Area of the region bounded by y=|x| and y=-|x|+2 is

The area of the region for which o lt y lt 3 -2x -x^(2) and x gt 0 , is

If x>0 and y<0, then the point (x, -y) lies in

The area of the region lying between the line x-y+2=0 and the curve x=sqrt(y)and y-axis , is
