The given diagram shows a circle with radius (R) 6 inches, and the central angle of arc AB as 30 degrees,
[tex]\begin{gathered} R=6 \\ \theta=30^{\circ} \end{gathered}[/tex]
Consider that the length (L) of a circular arc of radius R and central angle Θ, is given by the formula,
[tex]\begin{gathered} L=\frac{\theta}{360}\cdot2\pi R \\ L=\frac{30}{360}\cdot2\pi(6) \\ L=\pi \\ L=3.14 \end{gathered}[/tex]
