The side of a square 12 , the are of a square 12*12=144.
The radius of the circle is r=3. The area of one circle =πr²= 9π.
Area of 4 circles = 4*9π=36π  Green
Area that are left of the square after the circles would be painted green is
14436π  White
Green : White = (36π) : (14436π)
Green : White = (36π) : (36(4π))=π:(4π)
I should be π:(4π).
But they do not have this choice.
Maybe they typed it incorrectly and it is going to be π:(π4).
