Earth's circumference

Calculate the length of the circle of latitude at 48°10′ on Earth.

Final Answer:

x =  26728.1018 km

Step-by-step explanation:

R=6378 km α=48°10=48°+6010°=48.1667°48.1667   cos α = r/R  r=R cosα=R cos48.166666666667° =6378 cos48.166666666667° =6378 0.666966=4253.90952 km  x=2π r=2 3.1416 4253.9095=26728.1018 km
