-
a. The lighthouse's circumference is 10 X 2 X pi, or approximately 62.83m.
b. The fence's circumferences is 62.83 + 12.56 meters, or 75.39m
c. The radius of the fence is 75.39m / (2 X pi) or 12m
d. 12m - 10m, which is 2m
b. The fence's circumferences is 62.83 + 12.56 meters, or 75.39m
c. The radius of the fence is 75.39m / (2 X pi) or 12m
d. 12m - 10m, which is 2m
