A metal cylinder has a diameter of 20 cm. It has a density of 7900kg/m^3 and a mass of 24.806 kg. What is it's height.
-
density= mass/vol or vol= mass/density
vol= 24.806 kg/7900 kg/m3
vol=0.00314 m3= 3140 cm3
vol. cylinder= pi x r^2 h
3140 cm3= 3.1416 x 10^2 x h
h= 3140 cm3/3.1416 x 100 cm2
h= 10 cm
vol= 24.806 kg/7900 kg/m3
vol=0.00314 m3= 3140 cm3
vol. cylinder= pi x r^2 h
3140 cm3= 3.1416 x 10^2 x h
h= 3140 cm3/3.1416 x 100 cm2
h= 10 cm
