Areas of Simple Closed Curves In Exercises 87–92, use a computer algebra system and the result of Exercise 83 to match the closed curve with its area. (These exercises were based on “The Surveyor’s Area Formula,” by Bart Braden, College Mathematics Journal, September 1986, pp. 335–337, by permission of the author.)
(a) \(\frac{8}{3}ab\) (b) \(\frac{3}{8}\pi a^2\) (c) \(2\pi a^2\)
(d) \(\pi ab\) (e) \(2\pi ab\) (f) \(6\pi a^2\)
Hourglass: \((0\ \leq\ t\ \leq\ 2\pi)\)
