Answer:
![A=50.27\ cm^2](https://tex.z-dn.net/?f=A%3D50.27%5C%20cm%5E2)
Step-by-step explanation:
<u><em>The complete question is</em></u>
A circle with a radius of 3 cm sits inside of a circle with a radius of 5 cm. What is the area of the Shaded Region?
The shaded region is the area outside the smaller circle and inside the larger circle
we know that
The area of the shaded region is equal to subtract the area of the smaller circle from the area of the larger circle
Remember that
The area of the circle is equal to
![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
so
The area of the shaded region is
![A=\pi [r_1^2-r_2^2]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5Br_1%5E2-r_2%5E2%5D)
where
![r_1=5\ cm](https://tex.z-dn.net/?f=r_1%3D5%5C%20cm)
![r_2=3\ cm](https://tex.z-dn.net/?f=r_2%3D3%5C%20cm)
substitute
![A=\pi [5^2-3^2]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5B5%5E2-3%5E2%5D)
![A=\pi [16]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5B16%5D)
![A=16\pi\ cm^2](https://tex.z-dn.net/?f=A%3D16%5Cpi%5C%20cm%5E2)
assume
![\pi =3.1416](https://tex.z-dn.net/?f=%5Cpi%20%3D3.1416)
substitute
![A=16(3.1416)=50.27\ cm^2](https://tex.z-dn.net/?f=A%3D16%283.1416%29%3D50.27%5C%20cm%5E2)
