A shaft whose diameter is 10 cm rotates with an angular speed of 1.00 rad / second. Calculate the angular displacement IN RADIANS, if the shaft rotates for 3.75 seconds?? PLEASE HELP STUCK ON THIS> I know you convert the diam which comes to 0.05 m for RADIUS But don't know which formula to use tho?? THANKS for your help Joanne

The answer is pretty straightforward. I'm not sure what you're trying to do with finding the radius.
Each second, the shaft rotates by 1 rad. After n seconds, how many radians will the shaft rotate? Answer this and replace n by 3.75 to reach the answer.
