Find the radius of an aluminum cylinder that is 2.00 cm long and has a mass of 12,4 g. For a cylinder, V=πr^2h
Thank you
Would I just need to find the density of aluminum at room temperature?

Hello thebristolsoundYes, you will certainly need the density. Then use:
$\displaystyle \text{volume }= \frac{\text{mass}}{\text{density}}$When you have the volume, solve the equation
$\displaystyle V = \pi r^2h$for $\displaystyle r$; namely:
$\displaystyle r =\sqrt{\frac{V}{\pi h}}$Can you do it now?
