Thread: 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 ???

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
