Who discovered the earths curcumference?

Eratosthenes was the first to measure the Earth's circumference pretty acurately.


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.


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.


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).


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 percent error between polar circumference of the earth and real circumference?

There is no error. The Earth is NOT a sphere, it is an oblate spheroid. This is caused by the fact that it is spinning. The spin makes the middle (the equator) bulge out. Thus if you measure the radius to the equator it is 6,378.1 km, while if you measure the radius to a pole it is 6,356.8 km.


How do you measure the circumference of the earth?

Hm. You want the estimate or the actual data? The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers). However, if you measure the earth through the poles the circumference is a bit shorter - 24,859.82 miles (40,008 km). Thus the earth is a tad wider than it is tall, giving it a slight bulge at the equator. http://geography.about.com/od/geographyglossaryc/g/ggcircumference.htm
