inductive reactance!

guys how do u calculate the value of the rf choke using the inductive reactance formula, XL = 2∏fL .for example here u can see a schematic which transmits in a frequency 100Mhz,there u can see a choke!
my friend gave me this way to find out the value of choke
" 10kΩ inductive reactance would be fine.
That translates to
XL = 2πfL
10kΩ = 10000Ω
10000Ω = 2π(100M)L
L = 10000 / (2*∏*1e8)
L = 1e4/ (2*∏*1e8)
L = (1/6) 1e-4
L = 0.16e-4
L = 16e-6
L = 16µH."
so there fore the vakue of the choke should be 16μH.
but can u guys please tell me how did that 10kΩ come from.how did he take the 10KΩ from the circuit! please help me!
