What is the circumference of planet Earth?

"Earth's bulge also makes the circumference of Earth larger around the equator than around the poles. The circumference around the equator is 24,901.55 miles (40,075.16 kilometers), but around the poles it is only 24,859.82 miles (40,008.00 kilometers). The circumference is actually greatest just south of the equator, so Earth is slightly pear-shaped."

the radius of the Earth 6375.654784689 Km. There are many living things on it and it will not be ever counted exactly.

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).

it's approximately 6 m.\n\nthe formula that relates diameter and circumference is:\n\nCircumference = pi * diameter\n\n18.85 = 3.14 * d\n\n18.85/3.14 = d\n\n6.00 = d  <-- answer

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.

No, the circumference is nearer 24,900 miles at the equator, if by planet you mean Mother Earth.

The earth rotates about its axis.  Obviously at the poles, there is no speed to the rotation at all.  At the equator, the circumference of the earth is about 25,000 miles and it rotates once per 24 hours, so the speed would have to be 25,000/24 = 1041.67 mph.  Depending on where you are between the equator and the pole, you'll get a speed of between 0 and 1041.67 mph.

Here is a link of Eratosthenes experiment. You will understand it well looking at the drawing. In resume, he had to measure two shadows at the same time (obviously done with another person) in two distant places. He knew the angles and knew the distances between the points, so he could deduce the earths circumference.\nHis measurement gave a result between 36,700 and 46,900 kms, while the true circumference is  about 40,000 kms.\n\n\n---additin--\nForgot to paste the link, here it is\nhttp://www.juliantrubin.com/bigten/eratosthenes.html

The diameter of the Earth's orbit around the Sun is about 300,000,000 kilometers

The relative size of Earth, Jupiter, Sun = 1 : 10 : 100

Have you ever tried Google Earth, it is a good program that might let you get the circumference of countries.

circumference= 2*r*pi\nwhere r is the radius and pi is approximately 3.14

Equatorial Diameter: 7937 miles\nPolar Diameter: 7900 miles\n\nThe equatorial diameter is greater because the Earth is  spinning on it's axis (at about 1000 mph at the equator) which greats a centrifugal force pulling away from the center of the planet. This effectively lessens the gravitational pull at the equator and the equatorial regions of the planet bulge out.\n\nYou'll also find some other interesting solar system data at the site below.

32.675 AU for jupiter's circumference, and 2.406 AU for mercury.  Jupiter is the largest planet in our solar system.

the "smart kid" is incorrect about the size of the sun.  It is only 109 times larger than the planet earth.  The Sun's diameter is 864,938 miles (1,391,980 km). This is almost 10 times larger than the planet Jupiter and about 109 times as big as the Earth. The volume of the Sun is 1,299,400 times bigger than the volume of the Earth; about 1,300,000 Earths could fit inside the Sun.

Very similar to Earth's size.

It's about 1/6 earth gravity. (But don't forget to add in 1/6 of the spacesuit you have to wear, too.)
