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

\[ V = \pi r^2 h \]

where \(V\) is the volume, \(r\) is the radius, and \(h\) is the height.

  1. First, we need to find the radius. The diameter of the cylinder is 8, so the radius \(r\) is:

\[ r = \frac{diameter}{2} = \frac{8}{2} = 4 \]

  1. Now, we can plug the radius and height into the volume formula. The height \(h\) is given as 12.

\[ V = \pi (4)^2 (12) \]

  1. Now, calculate \( (4)^2 \):

\[ (4)^2 = 16 \]

  1. We can now substitute back into the volume formula:

\[ V = \pi \cdot 16 \cdot 12 \]

  1. Simplifying this gives:

\[ V = 192\pi \]

  1. Using \( \pi \approx 3.14 \):

\[ V \approx 192 \cdot 3.14 \approx 602.88 \]

Thus, the volume of the cylinder is approximately 603.19 when rounded.

So, the answer is \(603.19\).
