I typically would include the actual formulas you are using. I also tend to use the angular equations rather than trying to use the linear ones. For example: $$\displaystyle v = r \omega$$, so $$\displaystyle \omega = \frac{v}{r}$$ (And at this step you would do your unit conversions.)

Then you simply have $$\displaystyle \theta = \omega t$$.
