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 75 feet? (5 points)

1884 feet

4415.63 feet

58.88 feet

117.75 feet

Are you finding the arc length?

anonymous · Answer

Maybe.  I have no Idea on how to do this.

ivanzud · Answer

The arc length formula is 90/360*Circumference of circle(471.238898)=117.8

ivanzud · Answer

Which is answer D

anonymous · Answer

How did you find the circumference of the circle?

ivanzud · Answer

The arc length formula is actually $$\theta*r$$

anonymous · Answer

ok ThX.

ivanzud · Answer

Circumference formula is $$2 \pi*r$$
