A running meter of a hemp rope with a diameter of d 36 mm weighs 0.96 kg find the density
| August 6, 2021 | education
Initial data: l (length of the hemp rope) = 1 m; d (diameter of the hemp rope) = 36 mm (36 * 10 ^ -3 m3); m (rope weight) = 0.96 kg.
1) Calculate the volume of the hemp rope: V = l * S = l * 0.25 * Π * d ^ 2 = 1 * 0.25 * 3.14 * (36 * 10-3) ^ 2 ≈ 0.00101736 m3.
2) Find the density of the hemp rope: ρ = m / V = 0.96 / 0.00101736 = 943.6 kg / m3.
Answer: The density of the hemp rope is 943.6 kg / m3.
