What is the approximate circumference of the Earth?

  • (a) 20,000 kilometres
  • (b) 30,000 kilometres
  • (c) 40,000 kilometres
  • (d) 50,000 kilometres
The approximate circumference of the Earth is 40,000 kilometres, which corresponds to option (c).
  • The Earth is not a perfect sphere but rather an oblate spheroid, meaning it bulges slightly at the equator due to its rotation. Because of this shape, there are two primary measurements for its circumference:
  • Equatorial Circumference: The distance around the Earth's equator is approximately 40,075 kilometres.
  • Meridional (Polar) Circumference: The distance measured through the North and South Poles is approximately 40,008 kilometres.
