Answer:
Arc length is 12436.8m
Step-by-step explanation:
arc length = * πD
where M is the angle measure of the arc
and D is the diameter
considering the earth as a circle and half the earth as a semi circle the angle measure of the arc will be = 180 degrees
* π * 7917.5 = 12436.8m
It would be a 2:1 ratio because sides AC and DF are 8:4 which simplifies to 2:1
