Answer:

Arc length is 12436.8m

Step-by-step explanation:

arc length  = [tex]\frac{M degree}{360degree}[/tex] * 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

[tex]\frac{180}{360}[/tex] * π * 7917.5 = 12436.8m
