Light intensity varies inversely as the surface area of the sphere with the light source at the sphere's center.
Since the surface area of a sphere varies as the square of the radius:
A surface = 4 π r 2
Therefore the intensity of light varies inversely as the square of the distance from the light source (i.e. the radius).
