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

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

where:

  • \( V \) = volume
  • \( r \) = radius of the base of the cylinder
  • \( h \) = height of the cylinder

Given:

  • Height \( h = 12 \) inches
  • Diameter = 8 inches, so the radius \( r = \frac{diameter}{2} = \frac{8}{2} = 4 \) inches

Using \( \pi \approx 3.14 \):

Now, plug in the values:

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

Calculating:

  1. \( r^2 = 4^2 = 16 \)
  2. Volume calculation: \[ V = 3.14 \times 16 \times 12 \] \[ V = 3.14 \times 192 \] \[ V = 602.88 \text{ cubic inches} \]

So the correct answer is:

602.88 cubic inches.
