A circular oil spill in the ocean is increasing in diameter at a rate of 200 feet per hour. By how many square feet is the oil spill increasing per hour?
Increase in diameter: d(h) = 200h; h in hours
Increase in area: A(d) = π(0.5d)2; d in feet
Which composite function represents the total area of the oil spill as a function of hours?

Answer:

A(d(h)) = π(100h)2

Step-by-step explanation:

In edge it would be C

When solving these word problems it is helpful to remember that they ask us to use composition of functions to solve it so if it is the total area in regards to hours, what you would need to do look at the problem in this manner:  

A( (d(h) )= A (Pi(0.5x200h)^2

and when you simplify like terms it would be:

Pi(100h)^2
