Your question presumes that tree trunks are all circular. If you happen to find a circular tree trunk, you would measure around it to find the circumference.
If the tree trunk is not circular, you will not be able to find the circumference but, you can measure around it to determine its perimeter.

To determine the diameter of a tree, measure the circumference of the tree trunk at chest height (about 4.5 feet above the ground) and then divide that measurement by the mathematical constant pi (, approximately 3.14). The result will give you the diameter of the tree.

To determine whether a tree is a national champion, three criteria are typically used: height, crown spread, and trunk circumference. The tree must be measured for its height from the ground to the highest point, the crown spread is measured as the average width of the tree's canopy, and the trunk circumference is measured at a height of 4.5 feet above the ground. The tree that scores the highest based on a point system derived from these measurements is designated as the national champion for its species.
