Answer:

Arc length is 12436.8m

Explanation:

arc length =
(M degree)/(360degree) * 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


(180)/(360) * π * 7917.5 = 12436.8m
