The thickness (width or w) must be convert to cm(0.5mm=0.05cm), then find the Volume of the sheet.

The Volume is r2*pi*w or (20 cm)2(0.05cm) * pi i m sorry equals62.8319 cm3 or 63cm3 when considering the far-reaching digits.

You have to look up the thickness of aluminum somewhere. If youdid you would certainly probably find it to be somewhere roughly 2.70 gramsper cm3

Density(p)=mass(m)/volume(v)

If you multiply v through both political parties of the equation you will certainly havem=p*v

mass=(2.70g/cm3)(63cm3)=170.1g or considering the significantdigits 170 grams.
