How big is the earth in centimeters?
Mmm, well the Earth is round and not square, so it cannot be measure in a flat line, but has to be measured along the curve or around the circumference. The circumference of the Earth at the Equator, its widest point is 40,075 km (East/ West measurement). Its meridian circumference is 40,007 km (North/ South measurement - North Pole through the South Pole and back to the North Pole); which means the Earth is a little "shorter" than it is wide. There are 100 cm in 1 meter, multiply this by 1000 meters and you have 100,000 cm in 1 kilometer. Therefore: The equatorial circumference of the Earth is: 40,075 km x 100,000 cm = 4,007,500,000 cm The meridian circumference of the Earth is: 40,007 km x 100,000 cm = 4,000,700,000 cm; if you divide this by 2, this will give you the distance from the North Pole to the South Pole in cm, which is 2,000,350,000 cm
Why did greek scientist study the circumference of earth?
Greek scientists study the circumference of earth because science flourishes the Hellenistic era.
Eratosthenes determined the circumference of Earth by conducting an experiment Put his steps in order as they correlate to the scientific method?
State the problem: How can we prove Earth is round and calculate its circumference? Make a hypothesis: If the sun casts shadows at different angles at the same time of day in different places, we can determine how much Earth curves. Make observations and collect data: In Syene, the sun's rays are vertical at noon. At the same time in Alexandria, the rays are 7.2 degrees from the vertical.

How many meters around the world?
The circumference of the Earth at the Equator is 40,075.02 kilometres, or 40,075,020 meters.
Which contains all the information necessary to determine the circumference of the earth?
Two points, (a) and (b), 1000 km apart; the curvature of the earth between (a) and (b).
What did Eratosthenes determine?
He postulated the circumference of the earth.
How do you get the circumference of the earth?
The average radius of the Earth is 3,959 miles. The equitorial diameter of the Earth is about 7,926 miles. The ratio of the circumference to the diameter of a circle is written as the symbol pi. Pi is approximately 3.141592. Therefore, to determine the circumference from the diameter given above: equitorial diameter x 3.141592 = equitorial circumference = 7,926 x 3.141592 = 24,900 = The earth has a circumference of approximately 24,900 miles. More precisely the circumference of the earth at the equator is 24,902 mi. Remember that the earth is not a completely rounded sphere.
How do you determine the circumference of the earth if you know a circumference of a smaller latitude and the number of degrees the latitude is from the equator?
Circumference of the earth at particular latitude can be determined using the formula, Circumference of the earth = 2*PI*r*cos(Φ0) where r = radius of the at particular latitude r = R * (1 - ((1 / 298.25722356) * (0.5 - 0.5 * COS (2 * Φ0)))) R= radius of the earth at equator Φ0= latitude
What is the Earth's circumference in centimeters?
The circumference of the Earth is 4,007,500,000 centimeters (four billion, seven million, and five hundred thousand centimeters). See the Related Link below for more information.
How many times larger is the earth's circumference's than Luna?
The Earth is 3.64 times larger than Moon's Circumference. (Earth's Circumference) 39,843 divide by (Moon's Circumference) 10,921=3.64
Where is Earth's circumfrence greatest?
The circumference of Venus is very nearly the same as the Earth's. The Earth has a circumference of about 40,000 km while Venus has 38,000 km, making Venus' circumference about 95% the circumference of the Earth.
What is the circumference of the earth in inches?
== == Given that the circumference of the earth is 40,075.02 km (measured at the equator) the circumference in inches is roughly 1,577,756,664 inches.
When was the the circumference of the Earth first measured and by who?
One possible person is Eratosthenes of Cyrene ~230 BC as he was a Greek scientist who calculated the circumference of the Earth, with remarkable accuracy (some values for the "stadia" he used gives a result within 6% of the actual polar circumference). See link for further information
The earth has a diameter of 12756.32 km. What is the circumference of the earth?
Multiply the diameter by pi to find the circumference
What is circumference earth?
The circumference of the Earth at the equator is 24,902 miles. From pole to pole is 24,860 miles.
What is the distance of the circumference of the Earth?
