20 mm should still be 20 mm!
Circumference = 20*pi mm
20 sq cm = 20*100 sq mm = 2000 sq mm
Density is a measure of mass per unit volume. You need the mass and the volume of an object to be bale to calculate its density. There is no information about the mass. Furthermore, density is given in terms of grams per cubic centimetre, or grams per millilitre or similar. Density cannot be expressed in gram or cm.

what is the density of 40mm coarse Aggregate
1700 m3
The density of course aggregate is 1560 km/ m^3. The density of something can be found by dividing the mass by the volume.
2.64
Objects whose aggregate density is less than the density of water float in it. Objects whose aggregate density is greater than the density of water sink in it.
For plain cement concrete, the aggregate used is of size 20 mm. For RCC structures, it is 40mm and for roads, it is 80mm
If by aggregate you mean the 'rock' mixed in to make concrete, then the density is usually about 2.7 g/cm3 .
