A satellite orbiting the moon very near the surface has a period of 110 min.

What is the moon's acceleration due to gravity.

This is all the information that the problem gave. I feel like you can solve it if you know the radius of the moon, but they didn't so I'm stuck.
Well, it seems like the answer was 1.58 m/s^2, but I'm not sure how to get that answer, the method I used got me the wrong answer.
