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 is where r is the radius)

Explanation:

The formula for determining the volume of a spherical steel ball is expressed as

Volume = (4/3)πr³

Where

r represents the radius of the spherical steel ball.

π is a constant whose value is 3.14

Diameter = 9.4 mm

Radius = diameter/2 = 9.4mm/2 = 4.7mm

Volume = 4/3 × 3.14 × 4.7³

Volume = 434.67 mm³

Density = mass/volume

Mass = 3.475g

Density = 3.475/434.67

Density = 0.008 g/mm³
