Hello, I was wondering if anyone could help me with this PreCalc problem. Thank You!

(1 point) Let A =f(r) be the area of a circle with radius r and r = h(t) be the radius of the circle at time t. Which of the following statements correctly provides a practical interpretation of the composite function f(h(t)) ? Select ALL that apply if more than one is appropriate. A. At what time t the area will be A =f(r) B. At what time t the radius will be r = h(t) C. The length of the radius of a circle with area A =f(r) at time t D. The area of the circle which at time t has radius h(t) DE The length of the radius at time t The area of the circle at time t. G. None of the above If you don't get this in 3 tries, you can get a hint. int Think about what is the input and what is the output in the context of this problem.

Explanation / Answer

input of composite function is t i.e. time

output is area given by function f

so correct option is F
