From the order you gave me in the question the answer is equation number
4 1 3 2 6 5
Those are the equation numbers in ascending order based on their radius lengths
11x - 3 = 5x + 11
11x - 5x = 11+3
6x = 14
x = 14/6 =7/3
43 units
count all the square boxes. count the boxes covering more than half and leave the boxes covering less than half. I hope it's correct.
