Spherical Lune


LuneSurface

A sliver of the surface of a sphere of radius r cut out by two planes through the azimuthal axis with dihedral angle theta. The surface area of the lune is

 S=2r^2theta,

which is just the area of the sphere times theta/(2pi). The volume of the associated spherical wedge has volume

 V=2/3r^3theta.
