A circular puddle of liquid is evaporating and slowly shrinking in size. After t minutes, the radius of the surface of the puddle measures r(t)=18/2t+3 inches. The area A of the puddle is given A=r2. Express the area as a function of time finding (A o r)(t) and compute the area of the surface of the puddle a t=12 minutes.
