Arccccc lengththhththh

 

What is the length of the arc?     

 

The arc subtends a 60^o angle at the center,     

therefore the measure of the arc is also 60^o.     

 

A 60^o arc is 1 / 6 of the way around the circle.     

Given that the circumference of the circle is 1,     

the length of the arc is 1 / 6 unit.
