Subtract the volume of the inside diameter from the volume of the outside diameter and then multiply that by the density.
Volume of outside:
PI x 1.8^2 x 3.9 = 39.67704 cubic cm
Volume of inside:
PI x 1.35^2 x 3.9 = 22.318335 cubic cm
Difference: 39.67704 - 22.318335 = 17.358705 cubic cm.
Mass = 17.358705 x 8 = 138.86964 grams. Round the answer as needed.
If a quantity x is proportional (directly) to another quantity y, then x is written as x = ky, where k is called the Constant of Proportionality
A solid line would represent points on the graph that actually are included in the solution, while points that lie on dash lines aren’t included in the solution
Answer:
25 litres
Step-by-step explanation:

Answer:
The answer would be 5!
Step-by-step explanation:
22-7= 15
15/3 = 5
You can plug the 5 back in to check your work like so:
5 x 3 = 15
15 + 7 = 22
