1. Calculate the concrete cylinder's density using the formula [pi r^2h] to find volume and [mass /volume] to find density:

To calculate the density of a concrete cylinder, we need to know the mass and volume of the cylinder. The formula for the volume of a cylinder is given by , where is the radius of the base of the cylinder and is the height of the cylinder.Once we have the volume, we can calculate the density using the formula , where is the density, is the mass of the cylinder, and is the volume.Let's assume that the mass of the concrete cylinder is kg and the dimensions are m and m. Then, the density of the concrete cylinder can be calculated as: This formula will give the density of the concrete cylinder in kg/m^3.
