A school gym has a circular running track with a radius of 23 yards. Jerry runs around the track four times. Approximately how far has he run? Use 3.14 as the approximation of pi and round your answer to the nearest yard.

The perimeter of the circle is 2*pi*R = 2*3.14*23 = 144.44 yards
Distance = 4*Perimeter = 4*144.44 yards = 577.76 yards
