Acylinder has a density of 3.75g/cm3. if it has a mass of 12.1 g and a diameter of 8.22 cm, what is its height?

Given that  

Cylinder density = 3.75 g/ cm^3

Mass  of cylinder = 12.1 g

Diameter = 8.22 cm

Radius, r = diameter /2 = 8.22 /2 cm = 4.11 cm

Now calculate the volume as follows:

Volume = mass / density  

= 12.1 g/ 3.75 g/ cm^3

= 3.23 cm^3

Now with the use of volume of cylinder calculate the height as follows:

Volume of cylinder = πr^2h

3.23 cm^3 = 3.14 * (4.11 cm)^2 *h

h = 3.23 cm^3 / 3.14 * (4.11 cm)^2

=0.061 cm
