Work Step by Step

We find: Radius $r= \frac{d}{2}=\frac{2.40\,mm}{2}=1.20\,mm$ $=1.20\,mm\times\frac{1\,cm}{10\,mm}=0.120\,cm$ $V= \pi r^{2}h=\pi(0.120\,cm)^{2}\times15.0\,cm$ $=0.678584\,cm^{3}$ $\text{Density}=\frac{\text{mass}}{\text{volume}}=\frac{0.3624\,g}{0.678584\,cm^{3}}$ $=0.534\,g/cm^{3}$
