\omega_R = \frac 1 {sqrt{LC}}

f_R = \frac{\omega_R}{2\pi}

the formula of resonance frequency is
fr=1÷2π√ LC

fr = 1.3kHz

Unfortunately, copying and pasting don't work very well in this forum. I'm assuming you were trying to write

f_r=\frac{1}{2 \pi \sqrt{LC}}

which is the same thing as what I already wrote above.
