base 6 instead of base 10

It is my understanding that base 6 was used by ancient fertile crescent cultures.

if i understand it correctly base 6 was derived from creating consecutive rings of disks of a like size

1 in the center

6 in the first ring

12 in the next ring,

18 in the next, etc

comparing the area of a circle enscribing the second ring to the areas of the contained 7 disks(one in the center and 6 in the first ring) leaves a difference equal to two of the disks

and so on as you add more concentric rings of disks

..............

that being said

would base six be more appropriate for measurements in a circular plane

.......................

then on to concentric spheres of spheres of equal size

...........

is anything saved by utilizing a base derived from the shape (area or volumn etc.)of the thing defined?
