In physics, pressure is the amount of force exerted on a surface per unit area, P = StartFraction F Over A EndFraction The pressure, in atmospheres (atms), of a liquid on the circular base of a bucket is represented by the composite function (P ∘ A)(r), where and A(r) = πr². What is the domain of the composite function?
