arrange the circles (represented by their equations in general form) in ascending order of their radius lengths, x^+y^-2x+2y-1=0, x^+y^-4x+4y-10=0, x^+y^-8x-6y-20=0, 4x^+4y^+16x+24y-40=0, 5x^+5y^-20x+30y+40=0, 2x^+2y^-28x-32y-8=0, x^+y^+12x-2y-9=0.
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
