Express your answer in newton-meters. T = Submit ΠΙΑΣΦ I am having trouble converting. I have gotten up to (1900 rpm) (2 * 3.14 [pi] * rad/60 seconds). I have a TI 84 Silver Edition Graphing calculator and I've tried to find the "rad" function without using degrees since we don't know it at this point. Please assist.
