Answer:
[tex]13.735[/tex] [tex]ft^{2}[/tex]
Step-by-step explanation:
Area of a circle.
[tex]A=\pi r^{2}[/tex]
[tex]r=d/2\\r=8/2\\r=4[/tex]
[tex]A=\pi \times 4^{2}[/tex]
[tex]A=16\pi[/tex]
[tex]A \approx 50.2654824574[/tex]
Area of a square.
[tex]A=s^{2}[/tex]
[tex]A=8^{2}[/tex]
[tex]A=64[/tex]
Subtract the area of the square with the area of the circle.
[tex]64-50.2654824574[/tex]
[tex]= 13.7345175426[/tex]
I hope it helps.
Brainliest much appreciated.
