Question

3.The area of the square is 25. The area of the circle is 39. What is the area of the shaded regions?a. 14b. 56C. 64d. not enough information to determine

Answer 1

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:

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