Tree Sizes

Tree sizes

So the tree sizes I have marked so far are as follows. I have given each tree a number and marked that number on the tree so I can know what sizes exactly I am dealing with as the time comes closer to cutting them down and try and keep as close to the same size for each log as I can as it makes it easier to build that way.
The measurement given is in inches (circumference) and for those you are not familiar with Pi as I had pretty much forgotten what it can be used for, to come up with the diameter of the log its circumference divined by Pi. I am looking to have at least a 10 inch diameter log on the small end for each

Log::
(1) 40           (8) 31.5     (15) 31     (22) 36
(2) 38.5        (9) 36       (16) 32      (23)34.5
(3) 36          (10) 34       (17)  38     (24) 35
(4) 39.5       (11) 34       (18) 34     (25) 37
(5)  40         (12) 39       (19) 35     (26) 35
(6) 31          (13 48        (20) 38
.(7) 44        (14) 36        (21) 34
