Question

The figure below shows the ideal pattern of movement of a herd of cattle, with the arrows showing the movement of the handler as he moves the herd. The arc the handler makes from the starting point to the return point should be a quarter of a circle.

Based on this theory, what distance will the handler move from the starting point to the return point if he creates an arc of a circle of radius 80 feet?
Answer
62.8
83.73
125.6
or 502.4 feet

Answer 3

The circumference of the circle is C = 2pi*r = 2pi*80 = 160pi


A quarter of this is 160pi/4 = 40pi = 125.663706143591
