For this case, the first thing you should know is that the formula for the arc length is given by:
[tex]S = R * \alpha[/tex]
Where,
- R: radius of the circle
- α: central angle.
For this case we are going to assume that the correct data are:
[tex]R = \frac {36} {35}\\\alpha = \frac {2 \pi} {7}[/tex]
Substituting values we have:
[tex]S = \frac {36} {35} * \frac {2 \pi} {7}[/tex]
Calculated:
[tex]S = 0.923 cm[/tex]
Answer:
The arc length is:
[tex]S = 0.923 cm[/tex]
