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?. Answer. 21.25. 66.73 feet. 88.97 feet. 133.45 feet.
<span>The arc length in degrees (same as central angle that cuts it off) is to 360 (degrees in a circle) AS the arc length in linear measure is to the circumference of the circle (2 pi r).
90/360 = AL/[2 pi (85)] where AL is the arc length in linear measure.
1/4 = AL/[170 pi]
4 AL = 170 pi AL = 42.5 pi AL = 133.45 feet (approx)

<em>Step-by-step explanation: 70+70+70=210 and 40% for 210 students would add up to 120% of all students surveyed. Look if there is 70 students that's been surveyed that is 40% add 40% 3 times(40%+40%+40%)=120% of all students surveyed </em>
