  1. 15pi/6 * 180/pi = 15(180)pi/6pi = 15(180)/6 = 15(30) = 450

    Answer: 450 degrees.


  2. pi radians = 180 deg

    15pi/6 = (15/6)180 deg

    = 450 deg

  3. x/180 = 15pi/6pi

    x = 15 * 180/6

    = 450


  4. multiply by 180/pi

    15pi/6*(180/pi)

    the pi's cancel out.  You're left with (15/6)*180

    [15*(30*6)]/6

    15*30

    450 degrees
