The area of the shaded regions will be:


\text{Area}=\text{Area of circle - Area of the square}

Therefore:


\text{Area}=39-25=14

4.

BC is equivalent to the diameter of the circle, therefore:


\begin{gathered} A=\pi\cdot r^2 \\ \text{Where:} \\ r=(diameter)/(2) \\ r=(6)/(2)=3 \\ A=\pi(3^2) \\ A=9\pi \end{gathered}
