Answer 2

$\large{\underline{\underline{\bf{\red{QuEsTion}}}}}$

Volume of cylinder is 8 cm³ . if the density of cylinder is 290 g / cm³ . What is the mass of cylinder.

$\large{\underline{\underline{\bf{\red{AnSwEr}}}}}$

density = 290 g/cm³

converting it in kg/m³

$\bf{density=\frac{290*10^{-3}\:\;kg}{10^{-6}\:\;m^3}=290000\:kg/m^3}$

Volume = 8 cm³

Converting it in m³

volume = 8 * 10⁻⁶  m³

As we know,

$\boxed{\green{\bf{density=\frac{mass}{volume}}}}$

so , on putting values

$\mathrm{290000\:\:kg/m^3=\frac{mass}{8*10^{-6}\:m^3}}\\\\{\mathrm{mass=290000*8*10^{-6}\:\; kg}$

$\boxed{\large{\bf{\blue{mass=2.32\:\;kg}}}}$

Therefore,

the mass of cylinder will be 2.32 kg .
