Lets label circles as 1,2 and 3. i1,j1 are center coordinates of circle 1, i2,j2 & i3,j3 are center coordinates for circle 2 and circle 3 respectively.
We know equation for circle
(x - h)2 + (y - k)2 = r2
where h and k are x and y coordinates of center of circle.
x and y in above equation are x and y intercept of circle.i.e where circle has intersection with x-axis and y-axis.
and r is radius.
Using Equation for circles and solving the above figure
