7. Which of the following integrals would compute the area inside the inner loop for: 1 =4-8cos(0) (Hint: Graph first!!! This one is a bit tricky!) 5x/3 I. (4-8cose) de N II. 2 - (4-8cos0 ) de 0 III. (4-8cose ) do + [ - (4-8cose ) do N 5x/3 A) I only B) II only C) III only D) II and III E) I, II, and III F) None of these
