WebMay 2, 2013 · According to this RE chart, a circumference of 20,000km is approximately 3,300km to the north pole. If we put a 20,000km circle on the FE map, using the formula r=C/pi/2, where r is the radius, or distance to the north pole and C is the circumference of the circle, we get approximately 3,200km. Once again, real world distances match FET. As the string must be raised all along the entire 40,000 km (25,000 mi) circumference, one might expect several kilometres of additional string. Surprisingly, the answer is 2π or around 6.3 metres (21 ft). In the second phrasing, considering that 1 metre (3 ft 3 in) is almost negligible compared with the 40,000 km (25,000 mi) circumference, the first response m… WebDec 24, 2015 · The equatorial circumference of the Earth is 40,075 km.
