The length of the arc is directly proportional to the subtended angle.

If the subtended angle is changed from 70° to 10°, it means it has decreased by 60°.

Since the length of the arc is directly proportional to the subtended angle, we can calculate the new length using the ratio of the change in angle:

Change in angle = (10° - 70°) = -60°

If the length of the arc corresponding to 70° is x, then the length of the arc corresponding to 10° will be:

x * (-60°) / 70° = -0.857x

Therefore, the length of the arc corresponding to the 10° subtended angle will be approximately 0.857 times the original length of the arc.
