Mine was a formula, hun. :P
OpenStudy (anonymous):
formula, equation, meh
OpenStudy (anonymous):
\[Arc=2\pi*6*(\frac{ 60 }{ 360 })\]
OpenStudy (afrodiddle):
The arcs are congruent. So they divide the half circle (with angle of pi) in thirds.
To calculate arc length: r * theta = s
theta is the angle = pi/3

Sorry, forgot to add in the radius to the equation.
