Question 24
The radius of the $2$ identical circles is $3\text{ cm}$. They are inscribed in a larger circle of radius $9\text{ cm}$, as shown in the figure below. Find the area of the shaded region, in terms of $\pi$.
Answer-entry convention: enter the exact expression without units, using pi for $\pi$ and sqrt(3) for $\sqrt3$ (for example, a*pi-b*sqrt(3)).
