Lower Bound:

C = 404.5 mm

D = 125 mm

Upper Bound:

C = 405.5 mm

D = 135 mm

Circumference is rounded to the nearest 1mm, therefore when working out the boundaries for that you do +/- 0.5 (half of 1)

Diameter is rounded to the nearest 10mm, therefore when working out boundaries for that you do +/- 5 (half of 10)

Hope this helps :)
