Question 1133661
<br>
{{{57/60+36/60^2 = (57*60+36)/60^2 = 3456/3600 = 24/25}}}<br>
The radius of the circumscribed circle is the side length of the regular hexagon.  If we use P to represent the Babylonians' value for pi, and if the side length of the hexagon is s, then the perimeter of the hexagon is 6s and the circumference of the circumscribed circle is 2Ps.  So<br>
{{{24/25 = (6s)/(2Ps)}}}
{{{24/25 = 3/P}}}
{{{24P = 75}}}
{{{P = 75/24 = 25/8 = 3.125}}}<br>
The Babylonians' value for pi was 3.125.
