Could the Babylonians have done this?

FACT: The Babylonians estimated the value of pi to be 3 1/8.
FACT: Based on the Plimpton Tablet, we know that the Babylonians were aware of "Pythagorian Triples".

UNCERTAINTY (for me personally): The Babylonians method of establishing the value of pi is based on the perimeter of a hexagon inscribed within a circle. I am still searching for specifics as to how this determines the value of the perimeter of the hexagon to be 25/8.

QUESTION: Could this approximation of squaring the circle have been used by the Babylonians?

Squaring the Circle

I seriously doubt that this estimation method of Squaring the Circle is unique, but it's new to me. For further reading of this topic and many more, I strongly encourage you to purchase the text
