Question 6
In the diagram, $OC=10$ and $CD=16$. Find the shaded area. Leave your answer in terms of $\pi$.
Use the intended geometric relations shown: O is the centre of the large semicircle; CD is parallel to AB and tangent to the small semicircle. Both diameters lie on AB. These relations are shown pictorially rather than stated in words.
