Draw a line across the figure so that the total area of the circles is divided exactly in half.
need your guide .
thanks guys
Clearly, each region is going to have an area of 2 1/2 circles. You could simply draw a vertical line through the middle two circles such that the area is bisected...then you could compute the perpendicular distance between the line and the centers of the middle two circles.
This is not accurate. At an offset of 0.4 the approximate area of the segment is pi x 0.252316. It's certainly possible to calculate the correct position of the vertical line to greater accuracy, but you'd be hard pressed to actually draw the correct position of the vertical line to exactly cut the area in half.
