(a) What is the magnitude of the angular momentum of the disk?

I have τ= 16 N m and t= 0.033 s

I= 1.2e-3 kg m^2

In my book first of all there are two equations given for angular momentum (L)

Those are L= Iw and L=rp and I'm not sure which one I'm suppose to use. I have I but not w and I don't have r or p and p=mv correct? So I feel like this is actually a lot easier than I'm making it out to be but I can't get it. Any help will be greatly appreciated.
