inductive reactance XL = 2pi*fL

is this the same for inductor impedance?

i see on an example where they ask you to calculate the reactance in a series RL circuit. V= 100, f= 50Hz, R= 12 and L = 0.1H.

They ask to calculate calculate the reactance and impedance of the coil.

XL = 2pi*fL and impedance (Z) = sqrt(R^2+ XL^2) thats what they use to solve it.

when i check online for inpedance calculator http://www.pronine.ca/indimp.htm they use the inductive reactance formula to calaulate Z.

am a bit confused here, can someone plz clarify some of this. I havent done the lectures for this yet. thanks.
