mathmale · Answer

The formula for arc length is given by s= r(theta), or$$s = r \theta$$

mathmale · Answer

What is the radius of this particular circle?
What is the central angle, the one that defines the arc?
If the central angle is in degrees, you must change it into radians before using the formula $$s = r \theta$$.

Who looks worse, he who spells radius as radius or he who spells it as reduis?  
Effective communication requires correct spelling and grammar.  It's worth the effort to learn both.  Peace.
