since the distance between the earth and moon is and the amount of days it takes the moon to orbit earth is , we will have

But, the moon's orbit is elliptical, not circular. So, above result is close. It should be a larger than that because of the elliptical orbit as opposed to circular.
One way you could look at it is that the

of the moon is .
There are in a day, therefore
.
