If I have a given of Diameter = 12 inch time = 33 1/3 and asked to find the angular speed, w = theta / t how can I find the value of theta, is it automatically 2 pi ?

ganeshie8 (ganeshie8):

yup ! since it is taking 22 1/3 to rotate around. one rotation is always 2 pi rads

ganeshie8 (ganeshie8):

*33 1/3

wat they mean is, to make one rotation, the disk is taking 33 1/3 seconds

ganeshie8 (ganeshie8):

one rotation = 2 pi radians
