## Homework Statement

Calculate the density p and its uncertainty [tex]\Delta[/tex]p showing all working

Mass M (kg)

0.0163

[tex]\Delta{M}[/tex] (kg)

?

Diameter D (m)

0.014

[tex]\Delta{D}[/tex] (m)

?

## Homework Equations

[tex]\rho=MV[/tex]

[tex]p= \frac{6M}{\Pi{D}^3}[/tex]

[tex]Z=\frac{A^2B}{3C^{0.5}}[/tex]

[tex]\frac{\Delta{Z}}{Z}=\frac{2\Delta{A}}{A}+\frac{\Delta{B}}{B}+(1/2)\frac{\Delta{C}}{C}[/tex]

## The Attempt at a Solution

I have tried to use [tex]p= \frac{6M}{\Pi{D}^3}[/tex] but i don't think this is the equation to get the answer.

To find [tex]\Delta{p}[/tex], I don't understand how i can find [tex]\Delta{p}[/tex] if i do not have [tex]\Delta{m}[/tex] and [tex]\Delta{D}[/tex](which i don't understand how to get) from the equation:

[tex]\frac{\Delta{p}}{p}=\frac{\Delta{m}}{m}+\frac{\Delta{D}}{D}[/tex]

Hope someone can help me
