Question

Find the density of a 5.6-kg solid cylinder that is 15 cm tall with a radius of 3.2 cm

Answer 1

Answer:

Density of solid is $11605 kg/m^3$

Explanation:

Volume of the cylinder $V=\pi r^2h$

r=3.2 cm= 0.032 m

h=15 cm=0.15 cm

$V=\pi \times 0.032^2 \times 0.15\\V=4.825\times 10^{-4} m^3$

Density =Mass/ Volume

$\rho=\frac{m}{v} \\\rho=\frac{5.6}{4.825 \times 10^{-4}}$

$\rho=11605 kg/m^3$

Density of solid is $11605 kg/m^3$
