[SOLVED] oscillation frequency of circuit

1. The problem statement, all variables and given/known data

An L-C circuit containing an 83.0 $$\rm mH$$ inductor and a 1.50 $$\rm nF$$ capacitor oscillates with a maximum current of 0.800 A.

Calculate the oscillation frequency of the circuit.

2. Relevant equations
$$\omega$$ = $$\frac{1}{\sqrt{LC}}$$

$$f=2\pi\omega$$

3. The attempt at a solution

First I solved for omega

$$\omega$$ = $$\frac{1}{\sqrt{.083 H * 1.5*10^{-9} F}}$$
$$\omega$$ = 89622.14299

Then, since

$$f=2\pi\omega$$

I just plugged in omega.

$$f=2\pi*89622.14299$$ = $$563112.532 Hz$$

..

I typed in it, but it came back as incorrect. I looked and I can't find my mistake. I'm pretty sure I converted the units right and am using the right formulas. Can someone check to see if i did any thing wrong? Thanks.

Are you sure about your "relevant equations" ?
