Answer:

The volume is 144\pi.

Step-by-step explanation:

In order to calculate the volume of a cylinder, you have to find the area of it's base. Because a cylinder's base is a circle, you use the formula A=\pi r{2}. Substituting in the radius's length would be A=\pi (4){2}, which is A=16\pi. Now that we know the base area of the cylinder, we multiply it by the height, which is 9 to calculate the volume. Therefore, the volume of the cylinder would be 9×16\pi, which is 144\pi.
