A cylinder of lead has a mass of 14 kg. If the cylinder is 3 cm in diameter, calculate its height.

1 gram=1 cubic cm

14kg

kg=1000g

14kg=14000g

volume=14000

14000=volume

volume of cylinder=area of base times height

area of base=area of circle=pi times radius^2

2 times radius=diametert

radius=diameter/2

diameter=3

radius=3/2

radius=1.5

aprox pi to 3.14

14000 = (3.14 times 1.5^2) times h

14000 = (3.14 times 2.25) times h

14000=7.065 timtes h

divide both sdies by 7.065

1981.6=height

height=1981.6cm or 1.9816m
