Answer:
-12
Step-by-step explanation:
<u>Given</u>:
Given that the radius of the cylinder is 4 cm.
The height of the cylinder is 9 cm.
We need to determine the volume of the cylinder.
<u>Volume of the cylinder:</u>
The volume of the cylinder can be determined using the formula,

where r is the radius and h is the height of the cylinder.
Substituting π = 3.14, r = 4 and h = 9 in the above formula, we get;



Thus, the volume of the cylinder is 452.16 cm³
Hence, Option B is the correct answer.
If your asking what 9B coefficient is it's B
Yes that is a function because every number has a pair that goes to each other once
Answer: A proportional relationship needs to pass through the origin and have a linear (straight) slope. Let me know if you need more specifics.
