Please Help me Zach, Adam, and Carlos are working on an art project. They each cut a sector out of different size circles. Details about the sectors and circles are given below. Sort the three sectors in order of increasing area. Place the sector with the smallest area on top.

Zach's sector has a radius of 5 cm and a central angle of π/4 radians. Adam's sector was cut from a circle with an area of 72 cm2 with a central angle of π/6 radians. Carlos' sector was cut from a circle with an area of 36π cm2, a circumference of 12π cm, and an arc length of 5 cm.
