Surface area of a globe formula
WebApr 15, 2024 · There, they say it is simply 2 pi R*h, where h is the altitude between layers. First of all, I don't know how to determine altitude except at the equator where I can use a chord function C = 2R*sin (a/2), but you have to use twice the angle there and then take half the chord to get the altitude. WebAug 27, 2009 · 6 Answers. Sorted by: 13. There several ways to do this. 1) Integrate the contributions from latitudinal strips. Here the area of each strip will be (Rcos (A) (B1-B0)) (RdA), where A is the latitude, B1 and B0 are the starting and ending longitudes, and all angles are in radians. 2) Break the surface into spherical triangles, and calculate the ...
