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?

125.6 feet

502.4 feet

83.73 feet

62.8 feet

Answer 7

Pas de problème.

Answer 8

Donne-moi une secound.

Answer 9

...Yeah but no intention of replying.

Answer 10

Ok.

Answer 11

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


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


which is your answer
