Answer the following:

Problem No. 8: This is to solve the area enclosed by one petal (loop) of the rose r = cos 20. 53. Which of these represents the graph of the given rose curve? A B D 54. Setting up the definite integral that represents the area of one loop of the given rose as shown in Item No. 53. Note that the limits depend on the shaded region. Thus, area of one loop is represented as A. Area = _ cos 20d0 C. Area = 2 cos 20d0 B. Area = cos 2010 D. Area = 4 cos 20d0 55. What is the area of one loop that is asked in the problem? (2 points) A. 7t sq. U. B. sq. u. C. -sq. u. D. NA sq. U. 4 3
