We used different c _ _ _ _ _ _ _ _ _ _ _ to find the volume of this cylinder, but we both got the same result.

It seems like you are looking for a term that relates to methods or techniques used to calculate the volume of a cylinder. The most likely term that fits your description is "calculators." However, if you are looking for another word that fits within the context, "calculations" could also be a suitable answer.

To find the volume of a cylinder, you typically use the formula:

$V = \pi r^2 h$

where:

• $V$ is the volume,
• $r$ is the radius of the base,
• $h$ is the height of the cylinder.

Different calculators or methods might include using geometric principles, numerical integration, or computer software to achieve the same result, confirming the consistency and reliability of different calculation approaches.
