[SOLVED] Radian conversion.
how do you convert radians "in decimal form" to degrees?
I know you can do like
2pi rads = 2pi*180/pi cancel the pi's and you got 360 degrees as an answer.
But I wrote a test and a question was find the angle theta with radius 16cm and arc 32cm ****(this is what threw me off, I thought it had to be like 16cm(pi) or something)*****
so I used the formula the formula
theta=a/r and got 2 radians (not 2pi)
so I tried to put this into the formula to convert to degrees and got 360/pi????
THis was on a no calculator part of the exam so I got stuck, and thought it might have been like a trick question so the only thing I could think of was that thats 360/pi = 2pi/pi = 2degrees which cant be right because radians cant be equal to the degrees????
