Density = mass / volume
volume = height * area = height * pi * r^2
Density = mass / (height * pi * r^2)
Get out your calculator.

Volume of cylinder
= pi. r^2 . h = 3.1416 X 9 X 10 = 282.744 cc
Mass is 5 kg = 5000 g
Density = Mass / Volume = 5000 / 282.744 = 17.6838..g/cc

densidy = mass / volume
mass is already given, you need to find volume
V = pi * r^2 * h
V = 3.14 x (3)^2 * 10 cm^3
you can do the rest.

Volume of cylinder...
V = Ï*h*r^2
V = Ï*(10 cm)*(3cm)^2
V = 282.7 cm^3
Density...
d = mass/volume
d = (5 kg)/(282.7 cm^3)
d = 0.017687 kg/cm^3
