Answer:
Option a.
The approximate measure, in degrees, of the central angle is ![38.22\°](https://tex.z-dn.net/?f=38.22%5C%C2%B0)
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
we have
![r=15\ m](https://tex.z-dn.net/?f=r%3D15%5C%20m)
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
substitute
![C=2(3.14)(15)](https://tex.z-dn.net/?f=C%3D2%283.14%29%2815%29)
![C=94.2\ m](https://tex.z-dn.net/?f=C%3D94.2%5C%20m)
step 2
Using proportion
Find the central angle of the circle by and arc length of 10 m
Remember that the circumference of a circle subtends a central angle of 360 degrees
so
Let
x -----> the measure of the central angle in degrees
![\frac{94.2}{360}=\frac{10}{x}\\ \\x=360*10/94.2\\ \\x=38.22\°](https://tex.z-dn.net/?f=%5Cfrac%7B94.2%7D%7B360%7D%3D%5Cfrac%7B10%7D%7Bx%7D%5C%5C%20%5C%5Cx%3D360%2A10%2F94.2%5C%5C%20%5C%5Cx%3D38.22%5C%C2%B0)
