    Just curious, do you have your unit circle values for radians memorized, e.g. pi/6, pi/4, pi/3?

    type in 9pi/4 in radian mode. press 2nd function press the (change degree mode) button till it goes to degree and the conversion is done

    these are the answer choices.. A. 200π° B. 405° C. 160° D. 324°

    No problem. Okay, so let's put the value 9pi/4 into a whole number based on that. So, if 8pi/4 is equal to 2pi, 9pi/4 must be equal to 2pi plus pi/4, right?

    2pi is equal to 360 degrees, and pi/4 is equal to how many degrees, if pi is the angle of a semicircle, or 180 degrees?

    would it be 160 then

    Back, sorry. Sorry, but I don't believe so. If you divide 180/4, (because pi is 180), what do you get?

    Yup. So, adding together 2pi and pi/4, what would be your sum in degrees?

    you could also do the same as others were saying by using your calculator to converts, but it's good to know how to do it with radians because of their usefulness later on. Just to make sure, do you know how to do it on a calculator, like those dudes were saying?
