The diameter of Earth is 12.742 million meters. The radius of a sphere is 1/2 of the diameter. To find the radius of Earth, we'd need to divide...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your...
The Earth is about 7,926 miles (12,756 km) in diameter. The Earth is the fifth-largest planet in our Solar System (after Jupiter, Saturn, Uranus, and Neptune).Eratosthenes (276-194 BC) was a Greek scholar who was the first person to determine the circumference of the Earth...
If we accept the account of Strabo that Eratosthenes measured the circumference of the earth as 252,000 stadia, the circumference would be 24,662 miles, and the polar diameter 7,850 miles-only 50 miles short of the true polar diameter. This is considered to be one of the first great ...
Earth is classified as the largest of the terrestrial planets based on its circumference and diameter as well. At the equator, Earth's circumference is 24,901.55 miles (40,075.16 km). It is slightly smaller between the North and South poles at 24,859.82 miles (40,008 km). Earth's diamet...

in his location at Syene, which is present-day Aswan in Egypt, and that of a shadow in Alexandria was about 7.2 degrees. Since he knew the distance between the locations, he was able to determine the circumference of the earth, and therefore the diameter and radius as well. You can do...
2 它的周长约为25000 英里,其两极直径约为7900 英里,赤道直径为7927 千米 It has a circumference of approximately 25000 miles(40000km), a polar diameter of about 7900 miles (12714km), and an equator diameter of 7927 miles(12756km). 3 地球内部的三大圈层是地核、地幔和地壳。 The three main ...
Therefore, the diameter of Earth through its center is 7,926 miles (12,756 km). Again, because of the equatorial bulge, the planet's diameter is slightly smaller when measured from pole to pole, where it is about 7,900 miles (12,712 km). The equatorial circumference of Earth is 24,...
The equatorial diameter of the earth is 8,000 (7,926) miles and the circumference around the earth is 25,000 (24,830) miles. The earth is surrounded by atmospheric air up to about 100 miles deep, but most of the mass of air is within 10 miles from the earth’s surface. The...
