Answer:
The area of a circle in terms of its diameter is [tex]\frac{\pi d^{2}}{4}[/tex]
To find the area of the shaded region, determine the area of the largest circle and subtract the area of the four small circles.
[tex]A_{shaded}=\frac{\pi(8^{2})}{4}-\frac{\pi(2^{2})}{4}-\frac{\pi(3^{2})}{4}-\frac{\pi(5^{2})}{4}-\frac{\pi(1^{2})}{4}[/tex].
[tex]A_{shaded}=6.25\pi cm^{2} =19.63 cm^{2}[/tex]
