.
    The great-circle distance is the shortest distance between two points on the surface of a sphere, 
    measured along the surface of the sphere.


    Wikipedia,  https://en.wikipedia.org/wiki/Great-circle_distance


To calculate the requested distance, I used an online "great circle calculator" from the Internet site
https://www.cactus2000.de/uk/unit/massgrk.shtml


After inputting the given latitudes and longitudes, the calculator returned the distance of 10875 kilometers.
assuming the Earth radius of 6371.0 km.
