The formula for the volume \( V \) of a cylinder is given by:

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

where \( r \) is the radius and \( h \) is the height of the cylinder.

Given:

  • Height \( h = 12 \) inches
  • Diameter \( d = 8 \) inches

First, we need to find the radius \( r \):

\[ r = \frac{d}{2} = \frac{8}{2} = 4 \text{ inches} \]

Now we can calculate the volume:

\[ V = \pi r^2 h = 3.14 \times (4)^2 \times 12 \]

Calculating \( (4)^2 \):

\[ (4)^2 = 16 \]

Now substituting back into the volume formula:

\[ V = 3.14 \times 16 \times 12 \]

Calculating \( 16 \times 12 \):

\[ 16 \times 12 = 192 \]

So we have:

\[ V = 3.14 \times 192 \]

Now multiplying this out:

\[ V = 602.88 \text{ cubic inches} \]

Thus, the volume of the cylinder is:

\[ \boxed{602.88 \text{ cubic inches}} \]
