The volume of the steel bar is the product of the area of the cross-section and the length: π x r 2 x l = 3.1416 x 10 2 x 1000 = 314,160 mm 3 = 314.16 cm 3 (r = 1/2 x diameter, l = 1 m = 1000 mm). If using a carbon steel with density of 7.95 g/cm 3, we need the product of 7.95 and 314.16, which equals 2497.572 g, or ~2.498 kg.
