Answer:
A. 126pi cm^3
Step-by-step explanation:
The volume of a cylinder can be found using the following formula.

First, we must find the radius. The radius is half of the diameter.

The diameter of the cylinder is 6 cm.


The radius is 3 cm.
Now, we can substitute values into the formula.



Evaluate the exponent.


Multiply 9 cm^2 and 14 cm


The answer choices are in terms of pi, so we can simply rearrange our answer:

The volume of the cylinder is 126pi cubic centimeters and A is the correct answer.
