How do mathematicians measure shape perimeters?

When I create a circle on a computerized plane with a graphic editing program (such as Window's Paint), I can see a group of dots circling around an imagined central point.
if the perimeter is comprised of just one layer of dots we could always add another layer of dots on top of that first layer, and then a third one on top of the second layer, and so forth.
In CSS code it might be: border: 1px solid black and then 2px and then 3px.
In classical mathematics, how do mathematicians set or measure the perimeters (border thickness) of circles and other shapes that they draw on paper, or in a more daily life manner, if one has a pipe with the diameter of 3cm, how could that person measure its perimeter (circumference)?
