radius of 2 circles = 48 cm and 13 cm
let one circle be A having radius 48 cm and the other circle be B having radius 13 cm
circumference of circle A = (2 * 22/7*48) cm
=301.71 cm
circumference of circle B =(2*22/7*13)cm
=81.71cm
difference between the circumferences =(301.71-81.71)cm
=220 cm
so now lets consider a third circle C which has a circumference equal to 220 cm
therefore, A.T.P
2*22/7*r=220
r=35
therefore, area of circle C = (22/7*35*35)cm
=3850 sq.cm
