The density of a cone-shaped object can be expressed as ρ=3m/πr2h . A student measures the mass of the cone as (55.0±5)g , the radius as (2.3±0.3)cm , and the height as (11.0±0.4)cm .Part A Determine the absolute uncertainty δρ on the density of the cone. Round your answer to one significant digit.Part B Determine the percent uncertainty on the density ρ .
