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,
  • \( h \) is the height, and
  • \( \pi \) is approximately 3.14.

Given:

  • Height (h) = 12 inches
  • Diameter = 8 inches, so the radius (r) = diameter / 2 = 8 inches / 2 = 4 inches

Now, substitute the values into the formula:

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

Calculating \( (4)^2 \):

\[ (4)^2 = 16 \]

Now substitute back into the volume formula:

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

Calculating \( 16 \times 12 \):

\[ 16 \times 12 = 192 \]

Now substitute back again:

\[ V = 3.14 \times 192 \]

Now calculate \( 3.14 \times 192 \):

\[ V = 602.88 \]

Therefore, the volume of the cylinder is 602.88 cubic inches.

The correct response is:

602.88 cubic inches
