## What is the full circumference of the earth?

roughly 40,000 kilometers

## What is so interesting about the Earth’s circumference?

Circumference. However, the Earth is not quite a perfect circle, and if you measure through the poles, the circumference is a bit shorter—24,859.82 miles. The Earth is a bit wider than it is tall, giving it a slight bulge at the equator; this shape is known as an ellipsoid, or, more properly, a geoid.

What is the circumference of the earth according to Erastothenes?

24,662 miles
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 triumphs of scientific calculation.

### What are 10 interesting facts about the Earth?

How do you measure the circumference of the Earth?

If you like, you can calculate the Earth’s circumference yourself. The formula for calculating the circumference of a sphere is 2 x pi x radius. So, the radius of the Earth is 6371 km.

## Who estimated the circumference of Earth?

” Eratosthenes Teaching in Alexandria” by Bernardo Strozzi . The circumference of the Earth is 40,075 km, and the Greek geographer Erastosthenes was the first person to estimate the Earth’s circumference nearly accurately.

## What is the Earth’s circumference in miles and kilometers?

The circumference of the Earth in kilometers is 40,075 km, and the circumference of the Earth in miles is 24,901. In other words, if you could drive your car around the equator of the Earth (yes, even over the oceans), you’d put on an extra 40,075 km on the odometer.
