Question 2
Points $P$ and $Q$ are the centres of the circles shown. Chord $AB$ is tangent to the circle with centre $P$. Given $PQ\parallel AB$ and $AB=24$ cm, find the area of the shaded region.
The source does not specify a numerical approximation for π. For this practice question, compare the options using exact circle areas; the source-key convention is discussed after answering.
