Problem

An aluminium cylinder has a radius of

1.5\,\text{cm}

and a length of

20\,\text{cm}

. The density of aluminium is

2.7\,\text{g\,cm}^{-3}

. (a) Find the volume of the cylinder in

\text{cm}^3

. (b) Calculate its mass in kilograms. (c) Determine its weight in newtons, taking

g = 9.8\,\text{m\,s}^{-2}
