A circular diesel fuel spill is increasing in diameter at a rate of 400 feet per hour. The function for the increase in diameter is represented by f(h) = 400h, where h is hours. The function for the increase in area is represented by g(d) = π(0.5d)2, where d is in feet. Which is the composite function for the total area of the oil spill as a function of hours, h?
