Point F and C.
∆BCF

Let ∠ABC=x. According to the given condition ∠PQR=9x.
They are supplementary angles.
∠ABC+∠PQR=180°
Or,x+9x=180°
Or,10x=180°
Or,x=(180°)/10=18°
Thus,∠ABC=x=18°
∠PQR=9x=9×18°=162°

The diameter of the circle is 11 inches.
Radius of the circle = d/2=5.5 inches.
Area of the circle is given as
Area=πr^2=π(5.5)^2=30.25π sq.inch.
