. 7 When newspapers were printed by lithograph, the newsprint
had to run over three rollers, illustrated in the diagram by
three circles. The centres A, B and C of the three circles are
collinear.
The equations of the circumferences of the outer circles are
(x + 12) + (v +15) = 25 and (x – 24)² + (1 - 12) = 100.
Find the equation of the central circle.
