what is the circumference of the world?
367381
The Earth's circumference at the equator is 24,901.55 miles. Since the Earth rotates, it bulges outward at the equator, resulting in a measurement that is larger than if Earth did not rotate. Also, since it bulges at the equator, it contracts at the poles, resulting in a much smaller measurement than the equator: 24,859.82 miles.

In classical times, educated people pretty much understood that the Earth is a sphere.\n\n"Eratosthenes (276 BC - 194 BC) estimated Earth's circumference around 240 BC. He had heard about a place in Egypt where the Sun was directly overhead at the summer solstice and used geometry to come up with a circumference of 250,000 stades. This estimate astonishes some modern writers, as it is within 2% of the modern value of the equatorial circumference, 40,075 kilometres. However, the length of a 'stade' is not precisely known; Eratosthenes' figure falls short if we do not use a fairly generous estimate for this length." (http://en.wikipedia.org/wiki/Spherical_Earth)

What is the circumference of the Earth? How far around is the Earth?\n\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\nMore precisely the circumference of the earth\nat the equator is 24,902 mi / 40,076 km. \n\n------------------\n\nHow fast would you have to travel to see the sun set twice, \nor outrun the shadow of the setting sun?\n\nSince the sun "travels" once around the earth every 24 hours, \nwe can get the speed by dividing the circumference of the earth by 24:\n\nmiles divided by hours\n| |\n24,900 / 24 = 1,038 miles per hour\n\n....\n\nA RATIO of a to b can be expressed in three ways:\n1. a : b\n2. a / b\n3. a ÷ b

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).

Statistically the world average is between 5.7 and 6.2 inches.  Geographically and ethnically it is more diverse, but the physical norm is right about 6 inches.  Skinnier people look longer, fatter people look shorter.  There is a difference between growers and show-ers and all that, but average is six.

To answer this question, I'm going to assume the Earth is a perfect sphere.\n\nThe Earth's average radius is about 6.37*10^6 m. Then you can use trignometry to figure out the radius at 38 degrees north.\n\ncos(38 degrees)=r/6.38*10^6 m\nr is about 5.03*10^6 m\nTherefore the diameter is about 1.01*10^7 meters.

The circumference of the earth at the equator is approximately 24,902 miles.  This works out to about 40.16 times around.
