Calculated result for inductance seems wrong?
I think this is a mathematical error as I specified in a comment. To clarify further, rearrange for L as follows.

$$
L = \frac{(1e8*2\pi)^{-2}}{3e-11} = \frac{1}{12\pi^2} \cdot \frac{1e-16}{1e-11} = 8.443e-8 H = 84.43 nH
$$

The equation holds and seems to yield a reasonable value.
