Short of counting the triangles, and calculating from there... can someone tell me how to calculate the surface area of a Geodesic dome?

Re: How to calculate domes surface area?
Wed, February 22, 2006 - 1:01 PMIf you want an exact number then you will have to count each triangle. This is where Symmetry is your friend. Label each type of triangle, figure out how many you have on each face triangle of your polyhedra base (octahedron or icosahedron). Also pay attention to how you have the base divided.
If you are having problems send me some pics and dimensions and i'll help out.

Re: How to calculate domes surface area?
Thu, February 23, 2006 - 6:15 PMThe forumla for a sphere will get you there pretty quick it is more accurate for higher fequency domes.
(4pr^2) / 2
p= pi or 3.14
r= radius of dome
divide by 2 since it is a dome not a sphere. incidently if you have an odd frequency factor that in instead of dividing by 2. For instance a 3V 3/8 dome surface area would be 3/8(4pr^2) -
