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.
To convert 100 kg of 20 mm aggregate to cubic meters, you need to know the density of the aggregate. The density of aggregate can vary, but a commonly used value is around 1.5 tonnes per cubic meter. So, you would divide the weight (100 kg) by the density (1.5 tonnes/m³ = 1500 kg/m³) to get the volume in cubic meters. In this case, 100 kg / 1500 kg/m³ = 0.067 cubic meters.

unit wight of 20mm aggregate
The weight of 10mm aggregate varies based on the density of the aggregate material. On average, the weight can vary between 1400 to 1600 kg/m3, so for a specific weight, you would need to know the density of the aggregate material being used.
what is the density of 40mm coarse Aggregate
The weight of 10mm aggregate in 1 cubic meter depends on the density of the aggregate. On average, the density of 10mm aggregate is around 1.4 to 1.6 tonnes per cubic meter. So, the weight would be between 1,400 to 1,600 kg.
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.

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 .
