9.1~ft
Step-by-step explanation:
Formula for the area of a sector of central angle n (in degrees) and radius r:
![A = \dfrac{n}{360^\circ}\pi r^2](https://tex.z-dn.net/?f=%20A%20%3D%20%5Cdfrac%7Bn%7D%7B360%5E%5Ccirc%7D%5Cpi%20r%5E2%20)
We have:
A = 100 ft^2
r = 22 ft
We need to find:
r
![100 = \dfrac{n}{360^\circ}\pi (22^2)](https://tex.z-dn.net/?f=%20100%20%3D%20%5Cdfrac%7Bn%7D%7B360%5E%5Ccirc%7D%5Cpi%20%2822%5E2%29%20)
![n = 23.7^\circ](https://tex.z-dn.net/?f=%20n%20%3D%2023.7%5E%5Ccirc%20)
The central angle measures 23.7°.
Formula for the length of an arcs of a circle with central angle n (in degrees) and radius r:
![s = \dfrac{n}{360^\circ}2 \pi r](https://tex.z-dn.net/?f=%20s%20%3D%20%5Cdfrac%7Bn%7D%7B360%5E%5Ccirc%7D2%20%5Cpi%20r%20)
We have:
n = 23.7°
r = 22 ft
We need to find:
s
![s = \dfrac{74.4}{360}2 \pi (22 ft)](https://tex.z-dn.net/?f=%20s%20%3D%20%5Cdfrac%7B74.4%7D%7B360%7D2%20%5Cpi%20%2822%20ft%29%20)
![s = 9.1~ft](https://tex.z-dn.net/?f=%20s%20%3D%209.1~ft%20)
