(e) When newspapers were printed by lithograph, the newsprinthad to run over three rollers, illustrated in the diagram below bythree circles. The centres A, B and C of the three circles arecollinear. The equations of the outer circles are (x + 12)2 +(y+15)2 = 25 and (x−24)2 +(y−12)2 = 100. Find the equation of thecentral circle.
