Answer :
Final answer:
The density of the material used in the weight is calculated by dividing the mass (1kg) by the volume of the weight. The volume of the weight is calculated using the formula for the volume of a cylinder (π * radius^2 * height), which gives us about 0.000035 cubic meters. Thus, the density is approximately 28,571 kg/m^3.
Explanation:
To solve this question, we need to use the formula for the density (mass/volume). Given the description of the weight, we can calculate its volume using the formula for the volume of a cylinder, which is π * radius^2 * height. The radius is half of the diameter, so it would be 23.25mm or 0.02325m. The height is 41.5mm or 0.0415m.
The volume of the cylinder would thus be π * (0.02325m)^2 * 0.0415m, or roughly 0.000035 cubic meters.
Given that the mass is 1kg, we can calculate the density by doing 1kg / 0.000035 cubic meters. The result is approximately 28,571 kg/m^3, so the density of the material used in the weight is about 28,571 kg/m^3.
