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
Before:It's too short. Write at least 20 characters to explain it well.
After:It's too short. Write at least 20 characters to explain it well.
For the 12 sided one it would be 1/12
For the 6 sided one it would be 1/6
Combine those together and it would be <u>3/12</u> which is equal to <u>1/4</u>
