mercator
It is called a landform.
They project the surface of a sphere (the Earth) using a projection. Often the latitudes and longitudes are mapped onto the coordinate plane for small area but such projections distort shapes when mapping larger areas.
A globe or a sphere perhaps?
The surface area pf the Earth is on a sphere, not a flat surface.
Lets pretend that the Earth is a perfect sphere. Surface area of a sphere = 4(pi)(radius)^2. The radius of earth is 6378.1 km. Plug that into your equation and you'll get your answer.
