The surface area S (r) (in square meters) of a spherical balloon with radius r meters is given by S () = 4ar". The radius P (1) (in meters) after t seconds is given by P(1) =. Write a formula for the surface area N () (in square meters) of the balloon after t seconds. It is not necessary to simplify.
