The area of the circle by using ( A ∘ r ) ( t ) and interpret it, if an oil well is leaking with leak spreading oil over the surface as a circle. At any time, t in minutes, after the beginning of the leak the radius of circular slick on the surface is r ( t ) = 4 t feet and area A ( r ) = π r 2 , where r is the radius of the circle, t is time and A is the area of the circle.
