<h3>What is density?</h3>Density can be explained as a quantity having mass per unit volume and this can be calculated as:
Mass of the metal = ?
Density of the metal = 7.3 g/cm^3
height of the metal = 610 cm
radius of the metal = 8.7 cm
Volume of a cylinder can be calculated by using the formular below:
And this can be used by inserting the given values which is
Then we can calculate the mass as :
Mass = (density * volume)
=Since the cost is $0.38 per kilogram, then 3657 Kg costs
;( 1059003kg * $0.38)
= $ 402421
