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
  • \( \pi \) (pi) is approximately 3.14159.

Given:

  • Height \( h = 16 \) inches
  • Radius \( r = 4 \) inches

Now let's compute the volume:

  1. Calculate \( r^2 \): \[ r^2 = 4^2 = 16 \]

  2. Substitute \( r^2 \) and \( h \) into the volume formula: \[ V = \pi (16)(16) = \pi (256) \]

  3. Now, using the approximate value of \( \pi \): \[ V \approx 3.14159 \times 256 \approx 804.25 \text{ cubic inches} \]

Given the volume from the question is 604.56 cubic inches, we can conclude:

Since \( 804.25 \text{ cubic inches} \) does not equal \( 604.56 \text{ cubic inches} \):

The statement is False.
