    Need some help about a Steradian

    Hi, hmm I am just a liitle confused in this Steradian. Now I know that this works only with 3D. Now a radian is = arc of the size of a radius/radius So that 2*22/7*r/r = 360' 2*22/7rad = 360' 22/7rad = 180' Now that's how a radian is counted in 2D Is there any connection like this...
