This is my code calculating the distance from Geneva to (0,0). The output is 6825 km, differing from the real distance of ~5150 km I could not find what is wrong with it. Could someone check it please? Many thanks ```py import math lat1 = math.radians(46.2044) lon1 = math.radians(6.1432) lat2 = math.radians(0) lon2 = math.radians(0) dlat = lat2 - lat1 dlon = lat2 - lat1 dist = 2 * r * math.arcsin(math.sqrt(math.sin(dlat / 2) ** 2 + math.cos(lat1) * math.cos(lat2) * math.sin(dlon / 2) ** 2)) print(dist) ```
> `dlon = lat2 - lat1`\
