Let AB be the diameter of circle Γ1. In the interior of Γ1, there are circles Γ2 and Γ3 that are tangent to Γ1 at A and B, respectively. Γ2 and Γ3 are also externally tangent at C. This exterior tangent cuts Γ1 at P and Q, with PQ=20. The area that is within Γ1 but not in Γ2 or Γ3 is equal to Mπ. Determine M.

Let the radius of larger circle be a, smaller ones be 'b' and 'c'.
Ans = pie(a^2-(b^2+c^2)) here we are only concerned with (a^2-(b^2+c^2))=
(a^2 - ((b + c)^2 - 2bc) = 2bc as a=b+c
Using intersecting chord theorem,
2bc= AC*BC/4= PC*CQ/4= 10*10/4 as diameter bisects chord
= 50 Ans
