Antoine Mcconnell · Answer 1

The volume of a cylinder is PI*R^2H where PI is a regular, R is the radius and H the height. Consequently, the quantity of the iron rod could be (3.141) * ((2.05/2) ^2) * (ninety four. Three) = 311.2 cm^three. The density of Iron is 7.874 gm/cm^3, so the whole weight would be 2449 grams, or about 2.5 kilograms.
