The mass of lead cylinder is: 859.10 grams

Step-by-step explanation:

In order to find the mass of a cylinder we have to find the volume first

Given

Radius = r = 2 cm

Height = h = 6 cm

The volume of cylinder is given by:

$V = \pi r^2h$

Putting the values

$V = 3.14 * (2)^2 * 6\\= 3.14*4*6\\=75.36\ cm^3$

Now,

Density of lead per cm^3 = 11.4g

$Mass\ of\ cylinder = Volume*Density\\= 75.36*11.4\\=859.10\ grams$

The mass of lead cylinder is: 859.10 grams
