Answer:
The length of arc AB is 120 centimeters.
Step-by-step explanation:
Given information: O is the center of circle and radius of the circle is 4 centimeters. It is given that [tex]x=30^{\circ}[/tex].
Length of arc is
[tex]l=2\pi r(\frac{\theta}{360})=r\theta[/tex]
Since the radius of circle is 4 and [tex]x=30^{\circ}[/tex], therefore
[tex]AB=4\times 30=120[/tex]
Therefore the length of arc AB is 120 centimeters.
