what is the circumference of the world?
348973
The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers).\nBut, if you measure the earth through the poles the circumference is a bit shorter - 24,859.82 miles (40,008 km). This the earth is a tad wider than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like).

Earth is 12,742 kilometers (7,900 miles) in diameter.

Pi is the ratio of the diameter to the circumference of the circle.  Circumference = PI x diameter.\n\nThe arabs were the first to use it: they had a very good approximation at 22/7

pi is a greek word taht denotes 22/7 and pi is not exactly equal to 3.14:Actually 4 every possible circle in the world, when the circumference is divided by the same circle's diameter(d) the result is constant and equal to 22/7, which is a universal constant.It is from this basic idea that the circumference(c) of any circle C=pi*d evolved

You could use the formula for surface area of a sphere to solve this.\n\nUsing google, I found the diameter of the earth is 12756.3 km, which is equal to 41,851,378 ft.  So the radius is 20,925,689 ft.\n\nThe formula for surface area of a sphere is 4pi r².\n\nSo the square feet covering the earth is 4pi(20,925,689)² square feet.  \n\nThis is approx. equal to 5.5026 * 10^15 square feet.\n\n~ ♥ ~

2.5 meters becomes the circumference of the circle when you form the rope into that shape.  The formula used for determining the diameter of a circle when the circumference is known is: d=c/pi\n\nFor your question, d=2.5/pi\nTherefore, d=0.796 m

Circumference is 25,000 miles.  the diameter is about 7,950 miles, just under 8,000 miles (the earth isn't quite a sphere, it is a little pudgy at the equator, so the diameter varies slightly for our "oblique spheroid" which isn't a perfect sphere).

The circumference of the earth from pole to pole is roughly 24,860 miles. Since the distance of the north pole to the equator is 1/4 of the circumference then I calculate it to be approximately 6215 miles.\n\n:)

the circumference of the earth at the equator is exactally 24,902 mi (40,076 km)

Essentially, circumference is used to describe:\n\n1. The distance around a circle (picture a circle made up of a piece of string wrapped around, the circumference is the length of that string)\n\nand\n\n2. The distance around a sphere (a 3d version of a circle)\n\nCircumference is calculated using the formulae\nc = pi x d or c = pi x 2r where c = circumference, d = the diameter of the sphere or circle, r is the radius, and pi is approx. 3.14

By Most Accounts, 193 is the Correct Answer\nA very frequent geographical question is "How many countries are in the world?." Different numbers pop up when one inquires or reads about the number of countries in the world. Each source you use often yields a different answer.

Approx 12,451 miles.  See below (Divide the circumference by 2 since you are only going half way around the world)

"Diameter: \n Equatorial 12,756.274 km \n Polar 12,713.504 km \n Mean 12,745.594 km"\n\n"At the equator the diameter of the earth is 7927 miles; at the poles, it is very close to 7900 miles. 27 miles, a difference of 0.0034 is just enough to give mapmakers a headache."\n\n"the earth's diameter is 7,912 English miles"

circumference = pie times diameter\nradius is half of the diameter\n\nso if you have either the circumference or the diameter, you can figure it out.

I feel the question should be what is the circumference of earth -\nIt is -\nThe average radius of the Earth is 3,959 miles (6,374 kilometers).\nThe equitorial diameter of the Earth (distance from one side of the Earth to the other at the equator) is about 7,926 miles.\n\nThe ratio of the circumference to the diameter of a circle (circumference/diameter) \nis written as the symbol pi. \nPi is approximately 3.141592.\n3.14159265\n3.1415926535\n\nTherefore, to determine the circumference from the diameter given above:\nequitorial diameter x 3.141592 = equitorial circumference\n| |\n7,926 x 3.141592 = 24,900\n| |\nThe earth has a circumference of approximately 24,900 miles.\n\n\nMore precisely the circumference of the earth (or distance around earth)\nat the equator is 24,902 mi / 40,076 km. \n\nso the answer is 24,902 miles or 40,076 kms.

a classmate in my highschool geometry class came up with this one, as far as i know.  \n\nWhat is the formula for the circumference of a Pirate?\n\npi ARRRRRRRR 8.

The distance around the Earth, also known as its "circumference", is 24,906 miles = 1,578,044,159.9999997 inches.
