Question

The errors in the measurements of length,radius and mass of a cylinder are 3%,2%,and 0.5% respectively.The error in its density will be

Answer 1

Answer:

environmental or external error

Explanation:

These are the errors due to the environment by changing temperature, pressure, value, humidity

Answer 2

Answer:

Density =mass /volume

Density =m/(pi×r2×L)

dD/D=dm/m +2×dr/r +dL/L

=(0. 5+2×2 +3)%=7.5%
