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 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.
How many 30cm rulers would you need to measure the circumference of the world?
The Earth's circumference is approximately 40,075 kilometers, which is 40,075,000 meters. A 30 cm ruler is 0.3 meters long. To find out how many rulers are needed, divide the Earth's circumference by the length of the ruler: 40,075,000 meters ÷ 0.3 meters/ruler ≈ 133,583,333 rulers. Therefore, you would need about 133.6 million 30 cm rulers to measure the Earth's circumference.

Arab Astronomers determined that the earth was what?
Arab astronomers determined that the Earth was round in shape through a combination of observations and mathematical calculations. They also accurately calculated the Earth's circumference to an impressive degree of accuracy for their time.
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 perimeter of the earth?
The earth does not have a perimeter. The Perimeter is the distance around a circle. The earth is not a circle, but a sphere (sort of). The measurement around the earth is the circumference. Because the earth is not a perfect sphere, the circumference is different depending on whether you measure it horizontally (the equator) or vertically through the poles (Meridian).
How many 30cm rulers would you need to measure the circumference of the world?

Why would the circumference of earth have been helpful to the Greeks?
The Greeks could learn that Greece is not as big as the circumference of the Earth. This would lead to new countries, like America.
What is the s ize of the planet earth?
To find how big is the earth in miles, you can measure the circumference about the equator. This is approximately 24,900 miles. However, the circumference about the poles is slightly smaller at 24,859 miles.
Ertaosthenes determined the circumference of earth by conducting an experiment what are the steps?
Eratosthenes calculated the Earth's circumference by measuring shadows at two different locations at the same time. He then used the angles of the shadows cast by a vertical stick to calculate the Earth's circumference using geometry and trigonometry. By comparing the shadow angles at two different locations, Eratosthenes was able to estimate the Earth's size accurately.

How many times larger is the earth's circumference's than Luna?
The Earth's circumference is about 10 times larger than the Moon's circumference.
What is the measure of the earth's pull on an object?
The measure of the Earth's pull on an object is called its gravity, which is commonly quantified as the object's weight. This force is determined by the mass of the object and the mass of the Earth, as well as the distance between them.
