A regular hexagon and a regular octagon are both inscribed in the same circle.
Which of these statements is true?
Pictured is a hexagon inscribed in a circle to help you think about this question.

The perimeter of the hexagon is less than the perimeter of the octagon, and each perimeter is less than the circumference of the circle.

The perimeter of the octagon is less than the perimeter of the hexagon, and each perimeter is less than the circumference of the circle.

The perimeter of the hexagon is greater than the perimeter of the octagon, and each perimeter is greater than the circumference of the circle.

The perimeter of the octagon is greater than the perimeter of the hexagon, and each perimeter is greater than the circumference of the circle.

All perimeters are the same since they could all start and end at the same place.

Find the perimeter of ABCE.
(Hint: Place point D so that ABCD is a rectangle. You can then use trigonometry to find AE and DE. Round your answers to the nearest tenth.)
