A 50mm circle has a diameter of 50 millimeters, which is approximately 1.97 inches. The radius, which is half the diameter, measures 25 millimeters (about 0.98 inches). To find the area, you can use the formula A = πr², resulting in an area of approximately 1,963.5 square millimeters.
The easiest way to do this is to measure a large amount of paper sheets and to divide it. I have already done so the average is 0.049 millimeters per sheet.
1 meter = 1000 millimeters 1 millimeter = 0.001 meter
