What is the diameter of the Earth?
Kolkata, October 24: To mark the International Year of Planet Earth, a travelling exhibition Measuring Our Planet took off at the Birla Industrial and Technological Museum (BITM) in Kolkata on Friday. This is the first-of-its-kind initiative taken by the National Council of Science Museums (NCSM) where visitors can use scientific methods to measure the earth, said Ingit Mukherjee, director-general, NCSM. The exhibition will be held at eight Science centres across the country for the next two years. The earth exploration exhibit will teach visitors a number of techniques to explore various aspect of our planet. One can measure the diameter of the earth through scientific methods. For an instance, practical applications show that Indias population of 1,100 million can encircle the earth 50 times, said Jayanta Sthanapati, director of BITM. The exhibition also highlights modern techniques used in measuring the speed of rotation and revolution of the earth, studying the continental drift an

I really like the answer of 40,000/pi since a meter was defined as being 1/10,000,000 the distance from the equator to the north pole (passing through a city in france I think). And if you assume the earth to be round, we know that Circumference = pi * D therefore D = 40,000,000 m/pi The problem is that the earth is not a sphere so it varies in every location and doesn’t really have a diameter but any of these answers are close enough.
