<u><em>The picture of the question in the attached figure</em></u>
we know that
The area on the side of the house that is NOT covered by the light is equal to the area of semicircle minus the area covered by a spotlight on the side of a house
Find the area of the semicircle
The area of a semicircle is equal to
![A=\frac{1}{2}\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5Cpi%20r%5E%7B2%7D)
we have
![r=25\ ft\\\pi=3.14](https://tex.z-dn.net/?f=r%3D25%5C%20ft%5C%5C%5Cpi%3D3.14)
substitute
![A=\frac{1}{2}(3.14)(25)^{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%283.14%29%2825%29%5E%7B2%7D)
![A=981.25\ ft^2](https://tex.z-dn.net/?f=A%3D981.25%5C%20ft%5E2)
Find the difference
![A=981.25-954=27.25\ ft^2](https://tex.z-dn.net/?f=A%3D981.25-954%3D27.25%5C%20ft%5E2)
