A. The circumference of a circle is the actual length around the circle.
Circumference C = 2 pi r
r = 30, pi = 3.14
C = (2)(3.14)(30)
C = 60(3.14)
C = 188.4 for 1 lap
6 laps = 6 * C
6 laps = 6 * 188.4 meters
6 laps = ? meters
B. P = 2w + 2L
w = 37 cm./100 = 0.37 m
L = 5.2 m
P = 2(0.37) + 2(5.2)
P = ? meters
