Ans: ∠A =900

BC = 10cm; AB = 6cm;
∴ AC = 6cm

Area of the Δ =1/2 x 6 x 8= 24 cm2

Let the Radius of the Incircle be r

∴ 1/2 x 10 x r + 1/2 x 8 x r +1/2 x 6 x r = 24

1/2 r [10 + 8 + 6] = 24

r= 2 cm

∴ Area of circle = Π r2 = 22/7 x 2 x 2 = 88/7 cm2

Area of shaded region = 24 - 88/7 = 168 - 88/7 = 80/7 cm2
