2pi = 360
pi = 360/2 = 180 degrees
This means that pi/6 = 180/6 = 30 degrees
The formula for determining the length of an arc is expressed as
[tex]\begin{gathered} \text{length of arc = }\frac{\emptyset}{360\text{ }}\times2\pi r \\ \text{Given that }\emptyset=\text{ 30} \\ r\text{ = 1} \\ \pi\text{ = 3.14} \\ \text{length of arc = }\frac{30}{360}\times2\times3.14\times1 \\ \text{length of arc = 0.524} \end{gathered}[/tex]
