The solid angle cuts off a piece of the sphere. If we measure the area of this piece, and divide the area by the square of the radius of the sphere, then we have a measure of the solid angle in steradians. The surface area of a sphere is 4 pi times the square of the radius. Therefore the entire sphere has a solid angle of 4 pi steradians.
