Hello all! I just found this site and was hoping I could get some Trig help.
Could you please check my work?
given r=9cm and theta=120deg
Thanks for taking a look!
Not quite. Change 120 degrees into radians, and don't divide by 360. I think you are still thinking in terms of the sector being a ratio [fraction] of the entire circle, but that was done in developing the formula in the first place. Once you have the formula, and you do, just plug and chug, but DO use radians, not degrees.
