Radian measure

  1. May 23, 2013 #1
    Hi all,

    I have found this formula being used but I am not sure what it means. It is used to find the radius of a circle in a sector. Hope you can help me understand it.

    [tex]sin(π/6) = r/(6-r)[/tex]

    r is the radius of the circle itself and 6 is the radius of the sector or the circle of the sector. I may have to post an illustration if you can understand.

    Thank you.

    A sketch would be useful, indeed.
    I expect that the sketch shows what the formula means.
