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 85 feet?

a. 21.25
b. 133.45 feet
c. 66.73 feet
d. 88.97 feet

I wonder if the starting point and the return point are the same. I would think not.

I'm thinking that the arc length of the cowboy is to the circumference of the circle as the 90 degree quarter circle path is to the entire circle 360.

x/(2*pi*r) = 90/360   where x is the cowboy's distance.
