a horse is tied to a pole by a rope if the horse moves along a circular path keeping the rope tight and describe 176 m when it has traced out 72degree at the pole find the length of the rope

The 176 m line is a circular arc.
72 degrees is 1.2566 radians
176 m = 1.2566* R
Solve for R (rope length)
R = 140.06 meters
