Question 74754
You can convert radians to degrees by this formula:
{{{degrees=x*180/pi}}}
So if we plug in {{{x=2pi/9}}} we get
{{{degrees=(2*cross(pi)/9)*(180/cross(pi))}}}Notice the {{{pi}}} terms cancel.
{{{degrees=360/9=40}}}
So {{{2pi/9}}} radians equals 40 degrees. You were on the right track, but you needed to divide the {{{pi}}} terms.
