Question

A solid object in the shape of a cylinder is shown below.

Answer 1

Answer:

$0.08\ kg/m^3$

Step-by-step explanation:

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

#We calculate the volume of the cylinder:

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

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

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

Hence, the solid's density is $0.08\ kg/m^3$
