  • Answer:

    Get the volume by taking pi t r^2, noting that you are given the diameter, not the radius. Then multiply by the density of steel (or of iron, if your favorite crib sheet shows that but not steel). Note the units -- density is given in grams per cubic centimeter, not per cubic millimeter.

Weight (mass) = Volume * Density (Steel) Weight = Area of Disc * Thickness * Density Density of Steel = 7.8*10^-6 g/mm^3 Thickness= 2 mm Pi=3.14 D=Diameter of Round Disc Area = Pi*D^2/4 Area=3.14*760^2/4 = 453646 Weight= 453646*2*7.8*10^-6=7.1 g/mm^3
