What is the approximate circumference of the Earth at the equator?
The distance around the Earth at the Equator, its circumference, is 40,075 kilometers (24,901 miles).
What is the approximate circumference of the Earth?
In 200 B.C. Eratosthenes estimated Earth’s circumference at about 46,250 kilometers (28,735 miles). Today we know our planet’s circumference is roughly 40,000 kilometers (24,850 miles).
What is equatorial circumference?
Equatorial Circumference, also known as earth’s equatorial circumference is the linear distance of the earth around the equator. Due to this theory, the equatorial circumference of earth is more than its polar circumference.
Why is the Earth’s circumference larger around the equator?
The Earth is wider at the equator than from pole to pole, mainly because the centrifugal forces of its rotation make it bulge outwards. Satellites can measure its average shape using gravity and altitude data. Over most of the past 20 years, these observations showed that overall the Earth is becoming more round.

How did they calculate the circumference of the earth?
Eratosthenes then measured the angle of a shadow cast by a stick at noon on the summer solstice in Alexandria, and found it made an angle of about 7.2 degrees, or about 1/50 of a complete circle. Eratosthenes then used this to calculate the circumference of the Earth to be about 250,000 stadia.
What is the circumference of Earth hint apply the technique used by Eratosthenes to measure Earth’s circumference?
Eratosthenes hired a man to pace the distance between the two cities and learned they were 5,000 stadia apart, which is about 800 kilometers. He could then use simple proportions to find the Earth’s circumference — 7.2 degrees is 1/50 of 360 degrees, so 800 times 50 equals 40,000 kilometers.

How far is it around the Earth at the equator?
The Earth is widest at its Equator. The distance around the Earth at the Equator, its circumference, is 40,075 kilometers (24,901 miles).
What is the exact mileage of the Earth’s equator?
Earth’s circumference is the distance around the Earth. Measured around the poles, the circumference is 40,007.863 km (24,859.734 mi). Measured around the equator, it is 40,075.017 km (24,901.461 mi). Measurement of Earth’s circumference has been important to navigation since ancient times.
What is the distance around the Earth’s equator?
Earth’s circumference is the distance around the Earth, either around the equator (40,075.017 km [ 24,901.461 mi ]) or around the poles (40,007.863 km [ 24,859.734 mi ]).
