To calculate the weight of soil in the hole, you can use the formula for the volume of a cylinder, which is V = πr^2h, where r is the radius of the hole (which is half the diameter).

Given: Diameter = 2 meters Radius (r) = 1 meter Height (h) = 3 meters

Now, calculate the volume of the hole: V = π(1)^2 * 3 V ≈ 3.14 * 1 * 1 * 3 V ≈ 9.42 cubic meters

If the density of the soil is 1000 kg/m³ (a typical value for soil density): Weight = Volume * Density Weight ≈ 9.42 * 1000 Weight ≈ 9420 kilos

Therefore, the weight of the soil in the hole would be approximately 9420 kilos.
