# Tough or trick

Geometry Level 3

Two circles $$p$$ and $$q$$ which have the same radii of 7 cm intersect to each other and the distance between their centre, $$pq = 11 \text{ cm}$$.

$$ab$$ is a tangent line that touches the circle $$p$$ and $$q$$ at points $$a$$ and $$b$$ respectively.

Find the area of the shaded region ( in $$\text{cm}^2$$).

Use the approximation, $$\pi = \dfrac{22}7$$.
