Answer:
[tex]160 kg/m^3[/tex]
Explanation:
The density of the liquid is given by:
[tex]d=\frac{m}{V}[/tex]
where
m is the mass of the liquid
V is its volume
The mass of the liquid is
m = 1.0 kg
while the volume is the volume of a cylinder with height h=0.20 m and radius r=0.10 m:
[tex]V=\pi r^2 h = \pi (0.10 m)^2 (0.20 m)=6.28\cdot 10^{-3} m^3[/tex]
So, the density is
[tex]d=\frac{1.0 kg}{6.28\cdot 10^{-3} m^3}=159.2 kg/m^3 \sim 160 kg/m^3[/tex]
