The length of the arc between consecutive vertices is:
Step-by-step explanation:
The angle between consecutive vertices is 60°, it is because it forms an equilateral triangle.
Now, the length arc is defined as:
Where:
R is the radius (R = 8 in)θ is the angle of the arcWe see the angle is in grades, but we need to convert it to radians.
Finally, the length of the arc between consecutive vertices will be:
I hope it helps you!
