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.

Answer 1

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 feet
83.73 feet
125.6 feet
502.4 feet

Answer 2

The answer would be 62.8 because you take 80 divided by 2 equals 40 to find your radius then we use that for arc length so 90 over 360 equals 1/4. So our equation should look like this 1/4 *2(3.14)(40) and you get 62.8
