Maybe you want to say that if a radius is 4000 km, for a surface of 1000 km, the corners of this surface on the given sphere will be at a difference of about 31,496,588mm, that is 31.49km in front of tangent from the middle of the 1000km circle arc. That is, 31,496,588mm (31.49 km) distance from...

If a plane departs from the North Pole (where the Earth's rotation speed around its axis is 0 Km / h) on the median line to Romania, around the 45th parallel (where the Earth's rotation speed around its axis is 1178, 80 km / h) would the plane reach its destination only by flying to *South* (...
