Answer:
[tex]91659.02kg/m^3[/tex]
Explanation:
We have given mass m = 1 kg
Height of the cylinder [tex]h=49.5mm=49.5\times 10^(-3)m[/tex]
Diameter d=52.5 mm , so radius [tex]r=\frac{d}{2}=\frac{52.5}{2}=26.25mm=26.25\times 10^{-3}m[/tex]
Volume of the cylinder [tex]V=\pi r^2h=3.14\times (26.25\times 10^{-3})^2\times 49.5\times 10^{-3}=1.091\times 10^{-5}m^3[/tex]
We know that density [tex]d=\frac{mass}{volume}=\frac{1}{1.091\times 10^{-5}}=91659.02kg/m^3[/tex]
