Formula for finding the period of a pendulm?

T = 2*pi * Sqrt 1/g

Is this the proper formula for finding the period of a pendulm?

The length = 0.9 meters
g= 9.8m/s^2

I come up with 1.90s..
am I going in right direction?

Yes that's correct,though I think you have a typo in your formula:

$$T = 2\pi \sqrt{\frac{l}{g}}$$
