Using the formula
[tex] \frac{arc}{2 \pi r} = \frac{degree}{360} [/tex]
Isolate r
[tex]r= \frac{360arc}{2 \pi degree} [/tex]
Insert values and calculate r
[tex] r= \frac{360arc}{2 \pi degree} [/tex]
[tex]r= \frac{360(8)}{2 \pi 100} m[/tex]
[tex]r= \frac{2880)}{200\pi } m[/tex]
[tex]r= \frac{14.4}{\pi } m[/tex]
[tex]r= 4.563 m[/tex]
