Final answer:
The length of the arc intercepted on the circumference of the circle is 1.061 m.
Step-by-step explanation:
The length of an arc intercepted on the circumference of a circle can be calculated using the formula:
Length of Arc = Radius x Angle in Radians
In this case, the radius of the circle is 1.56 m and the angle between the two radii is 0.680 rad. Therefore, the length of the arc is:
Length of Arc = 1.56 m x 0.680 rad = 1.061 m
