Answer:

[tex]0.08\ kg/m^3[/tex]

Step-by-step explanation:

Density is defined as mass of an object divided by its volume.

#We calculate the volume of the cylinder:

[tex]V=\pi r^2 h, r=D/2=6/2=3\ cm\\\\=3.14\times 3^2\times 7\\\\=197.82\ m^3[/tex]

Given the mass= 15.3kg and volume as above, we calculate density as:

[tex]\rho=\frac{Mass}{Volume}\\\\=\frac{15.3\ kg}{197.82\ m^3}\\\\=0.0773\approx 0.08\ kg/m^3[/tex]

Hence, the solid's density is [tex]0.08\ kg/m^3[/tex]
