To calculate the circumference of the Earth, you can use the formula C 2r, where C is the circumference, is a constant (approximately 3.14159), and r is the radius of the Earth. The average radius of the Earth is about 6,371 kilometers. Plug this value into the formula to find the circumference.

What is the equatorial circumference of earth in miles?
The equatorial circumference of the earth is 24901.45 miles (40075.02 km).
Eratosthenes determined the circumference of Earth by conducting an experiment. Put his steps in order as they correlate to the scientific method?
Make observations: Eratosthenes observed that the sun cast shadows at different angles in different locations. Formulate a hypothesis: He hypothesized that the Earth was spherical and that he could calculate its circumference using the angle of the sun's shadows. Test the hypothesis: He measured the angle of the shadow in Alexandria and used this to calculate the circumference of the Earth. Analyze the results: By comparing his calculated circumference to the actual distance between Alexandria and Syene, he was able to estimate the Earth's circumference with remarkable accuracy.
Who was the first person to calculate the earth circumference?
The first person credited with accurately calculating the Earth's circumference was the ancient Greek mathematician and astronomer Eratosthenes in the 3rd century BC. He did so by measuring the angle of the sun's rays at two different locations and using simple geometry to estimate the Earth's size.
What is the circumference and diameter of Earth in miles?
The circumference of the earth in miles is about 24,901 miles. The diameter is about 7,926 miles.
When was earth diameter first estimated?
Eratosthenes of Cyrene (276 BC - 194 BC) was a Greek mathematician, poet, athlete, geographer and astronomer. He made several remarkable discoveries and inventions: he devised a system of latitude and longitude. He was the first person to calculate the circumference of the Earth with remarkable accuracy, and the tilt of the earth's axis.
Who is calculate the circumference of earth?

When did euratosthenes calculate the circumference of the earth?
It is not known when, or even if, Euratosthenes did calculate the circumference of the earth. However, it is known that a very accurate estimate was obtained by Eratosthenes in the early years of the third century BC.
What year did eratosthenese calculate the circumference of the earth?
Around 240 BC.
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
Who invented area and circumference of a circle?
Actually, Eratosthenes of Cyrene (276? - 195? B.C.) was the first to calculate the Earth's circumference accurately. He is supposed to be the inventor.
Contribution of eratosthenes?
Eratosthenes had many contributions : he was the first person to calculate the circumference of the earth he invented latitude and longitude he was the first person to prove earth was round he was the first to calculate the tilt of Earth's axis
How can altitude be used from 2 different locations to calculate the circumference of the earth?
Altitude measurements taken from two different locations can be used to calculate the circumference of the Earth using trigonometry. By measuring the angle of elevation to the same point in the sky from the two locations and knowing the distance between them, it's possible to calculate the circumference. This method is based on the principles of triangulation and spherical geometry.
What did eratosthenes create?
He invented the system of longitude and latitude.He was too the first person who calculate the circumference of the Earth.
What measure could the circumference of the earth be determined?
The circumference of the Earth can be determined using the method of measuring the angle of the sun's shadow at two different locations at the same time. By knowing the distance between the two locations and the angle of the shadow, one can use basic trigonometry to calculate the Earth's circumference. This method was famously used by Eratosthenes in ancient Greece, who estimated the Earth's circumference with remarkable accuracy.
How do you calculate circumference?
to calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. the you have circumference!
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
How can you put the word circumference in a sentence?
His prime objective was to measure a degree on the equator to calculate the circumference of the earth.Studies have shown there has been a large increase in waist circumference in young people.The earth's circumference was accurately measured around 240 BCE by Eeratosthenes.It isn't easy to measure the circumference of large items.
