Mrs. Lubek exercises her horse by walking him around a circular track. The distance from the edge of the track to the center of the circle is 150 ft. If Mrs. Lubek walks her horse 4 times around the track, approximately how many feet will she and the horse travel? (Use π = 3.14.)
Find the circumference of the circle....this is the length of the track
pi * d = circumference
pi * d = pi * 2r
pi * 2 (150) = 942.477 ft around the track
four times around would be 4 * 942.477 = 3769.91 ft ~~3770 ft
