The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2. "r" is the radius; if you find the diameter of Earth somewhere, divide it by 2 to get the radius.The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2.

The Prime Meridian does not divide the Earth, it is an imaginary line going straight through the center.

To divide the earth
Scientists use latitude and longitude lines to divide the Earth into sections. These lines create a grid system that helps pinpoint specific locations on the Earth's surface.
fossil records
Geographers divide the earth using hemispheres.

One half of 23422 is 11711. Why on earth would you use wikianswers to divide by 2?
The Prime Meridian does not divide the Earth, it is an imaginary line going straight through the center.
The equator divides the Earth into two. Each half is called a hemisphere. The equator divides Earth into northern and southern hemispheres. The prime meridian and the 180 dgrees meridian divide Earth into eastern and western hemispheres.
They are landmasses on Earth just like parts of the Earth. They are to divide earth into landmasses.
Longitude lines run north-south and divide the Earth into the Eastern and Western Hemispheres, while latitude lines run east-west and divide the Earth into the Northern and Southern Hemispheres. The intersection of latitude and longitude lines creates a grid system that helps identify specific locations on Earth.
Meridians
Divide the circumference of the earth by (2x3.14) and that's roughly the answer.
