John Lloyd runs around the perimeter of a circular track at 9 ft/sec. The track has a radius of 90 yd After 25 seconds, John Lloyd turns and runs to the center of the track along a straight (radial) line. Upon reaching the center, he turns and runs away along a different radial line to his starting positio on the perimeter. (a) How far has John Lloyd traveled once he has returned to his starting position? distance = feet (b) How much time will it take for John Lloyd to complete his circuit? time = seconds (c) Find the area of the pie-shaped sector enclosed by John Lloyd's path. area = sq-yd
