    converting radian measure to degrees

    i need to convert the radian measures to degrees:

    a) 2
    b) 3
    c) pi^2

    ok i know pi is 180 degrees so i did

    2/180 = x/pi and i solved for x and got the right answer but isn't there a simpler way to do it ???

    (radians) \times \frac{180}{\pi} = (degrees)

    Trying to Help

    I don't really understand your problem, but this is what I know, maybe it will help.

    The arc length is directly proportional to the angle subtended at the center by the arc.

    i.e. Arc length/Circumference=angle subtended at the center/360

    or Arc length=angle subtended at the center/360 times circumference

    for any circle with radius r, if the angle subtended at the center by an arc is x, then the arc length is

    Arc Length=x/360 times 2(pi)r
