# A spherical steel ball has a mass of 3.475 g and a diameter of 9.40 mm. What is the density of the steel? |The volume of a sphere = (4/3)πr3 where r = radius.]

Interpretation Introduction

Interpretation: The density of steel has to be given.

Concept Introduction:

Density: is a characteristic property of a substance.  The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume).

Density = MassVolume

Explanation

The density of steel is calculated as,

Given:â€‰MassÂ =Â 3.475g;â€‰â€‰diameterÂ =â€‰9.40mmÂ =Â 0.94Â cm;Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â radiusÂ =Â 0.47Â cmVolumeÂ ofÂ sphereÂ =Â 43Ï€r3Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â =Â 43(3
