First, find the area of the shaded circle.
8π^2
64π
Then find the area of the square using 45 45 90 relationships.
16
16/2^1/2
16(2^1/2)/2
8(2^1/2)
Now subtract.
64π-8(2^1/2) is you answer.

Mathematics

72.96 ${in}^{2}$

Step-by-step explanation:

Radius = 8 in ( Given)

Area of shaded part:

Area of circle - Area of square

$(\pi \times {(8)}^{2} ) - ( \frac{16}{ \sqrt{2} } ) ^{2}$

$= (3.14 \times 64) - \frac{256}{2}$

= 200.96 - 128 $= 72.96 \: {in}^{2}$

Hope this helps...

Good luck on your assignment

$\bf \textit{arc's length}\\\\ s = \cfrac{\pi \theta r}{180}~~ \begin{cases} r=radius\\ \theta = \stackrel{central}{angle}~in\\ \qquad degrees\\[-0.5em] \hrulefill\\ r=2\\ s=5.45 \end{cases}\implies 5.45=\cfrac{\pi \theta (2)}{180}\implies 5.45=\cfrac{\theta \pi }{90} \\\\\\ 490.5=\theta \pi \implies \cfrac{490.5}{\pi }=\theta \implies \stackrel{degrees}{156.13\approx \theta }~\hfill \stackrel{radians}{2.72\approx \theta }$
