The page that this assignment is printed on is to be folded to form an open cylinder with a 1 cm overlap.

1. Measure the length and width of this page to the nearest millimetre. What will be the circumference of the base circle of the open cylinder? Use this measurement to find the radius of the base circle of the open cylinder.

(I measured this - Length: 296 mm; Width = 210 mm). I am aware this this question may seem overly simple to you, but I cannot seem to understand what I have to do. I keep calculating the incorrect answer. Any help, if you can do so, is appreciated. Thank you in advance!
