1. Measure the thickness of 10000 papers, then divide the thickness by 10000 to get the thickness of 1 paper

2. Hold 10000 thin wires to make it like a "cylinder", measure the area of the cross-section of this cylinder, divide it by 10000 to get the area of 1, divide it by pi and take its square root to get the radius, multiply it by 2 to get the diameter
