 The area of the circular segment by definition is:
 A = 0.5r ^ 2 (a - sin (a))
 Where,
 r: radius of the circle
 a: angle
 Substituting we have:
 For the largest circle:
 A = 0.5 (10 ^ 2) [(60) (pi / 180) - sin (60)]
 A = 9.0586 in ^ 2
 For the smallest circle:
 A = 0.5 (6 ^ 2) [(90) (pi / 180) - sin (90)]
 A = 10.27 in ^ 2
 Total area:
 A=10.27+ 9.0586
 A=19.3286

She should use 12/3 to measure
