Answer:
Step-by-step explanation:
The formula for determining the volume of a sphere is given as
Volume = (4/3) πr³
where r is the radius and π is a constant whose value is 3.14
From the information given,
Diameter = 9.4 mm
Radius = diameter/2 = 9.4/2
= 4.7 mm
Volume of sphere = 4/3 × 3.14 × 4.7³
= 434.67 mm³
The formula for determining density is expressed as mass/volume
Mass = 3.475 g
Density = 3.475/434.67 = 0.008g/mm³
Discriminant = b^2 - 4ac
a = 4
b = 16
c = 16
16^2 - 4(4 x 16)
256 - (4x64)
256 - 256 = 0
Therefore it only has one root
