A ball of radius  r  has volume V(r) = π r3  cubic units. This volume can be regarded as a sum of volumes of concentric spherical shells having radii  x  units (where  0 ≤ x ≤ r)  and thickness  dx.  Use this fact to find the surface area  S(r)  of a sphere of radius  r.
◦ S(r) = π r2  square units
◦ S(r) = 2 π r2  square units
◦ S(r) = 4 π r2  square units
◦ S(r) = 8 π r2  square units
◦ S(r) = 8 r2  square units
