What is over 40000 km at its circumference?

Eratosthenes knew that on the first day of summer, the Sun passed directly overhead at Syene, Egypt. This means that Eratosthenes estimated the circumference of the Earth to be about 40,000 km. He also knew that the circumference of a circle was equal to 2 times π (3.1415…) times the radius of the circle.

What is the approximate circumference of the Earth group of answer choices?

For one thing, he was using as his unit of measure the Greek unit “stadion,” or the length of an athletic stadium. But not all stadiums were built the same length. In Greece a stadion equaled roughly 185 meters (607 feet), while in Egypt the stadion was about 157.5 meters (517 feet).

What is the radius of the Earth?

3,958.8 mi
Earth/Radius
According to data taken by 183 high-school classes participating in a World Year of Physics project, “Measure the Earth with Shadows”, the radius of Earth is 6563 km, compared to the accepted value for the mean radius of 6371 km. Of course, no one is claiming the size of Earth has actually changed.

How many kilometers is the circumference of Earth?

40,075 km
Using those measurements, the equatorial circumference of Earth is about 24,901 miles (40,075 km). However, from pole to pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around.

How many km is the Earth?

Using those measurements, the equatorial circumference of Earth is about 24,901 miles (40,075 km). However, from pole to pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around. Our planet’s shape, caused by the flattening at the poles, is called an oblate spheroid.

What is the circumfrence of the Earth in meters?

The circumference of the Moon is 10,921 km, and the circumference of Jupiter is 500,000 km. Here are a bunch of measurements for you: Circumference of the Earth in kilometers: 40,075 km. Circumference of the Earth in meters: 40,075,000 meters. Circumference of the Earth in centimeters: 4,007,500,000 centimeters.

What is the circumference of the globe?

The circumference of the globe is approximately 40 000 km. If we made a circle of wire around the globe, that is only 10 metres longer than the circumference of earth, could a flea, a rabbit or even a man creep under it?

What are the measurements of the Earth?

Earth’s Measurements. With a circumference of 40,075 km, Earth is the fifth largest of the planets in the Solar System. The meridional circumference that is from pole to pole is 40,008 km. The difference is caused by the flattening of the poles, such that the Earth has an oblate spheroidal shape.

What is the circumference of the Earth around the equator?

Measured around the Equator, it is 40,075.017 km (24,901.461 mi). Measured around the poles, the circumference is 40,007.863 km (24,859.734 mi). Measurement of Earth’s circumference has been important to navigation since ancient times.
