To find the volume of the peanut butter jar, we first need to determine if the jar is modeled as a cylinder, which is a common assumption for jars.

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

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

where:

  • \( r \) is the radius of the base of the cylinder,
  • \( h \) is the height of the cylinder,
  • \( \pi \) is approximately 3.14.

Given:

  • Height (\( h \)) = 16 cm
  • Width = 10 cm, so the radius (\( r \)) = width / 2 = 10 cm / 2 = 5 cm.

Now we can substitute the values into the volume formula:

\[ V = 3.14 \times (5)^2 \times 16 \]

Calculating \( (5)^2 \):

\[ (5)^2 = 25 \]

Now substituting back into the volume formula:

\[ V = 3.14 \times 25 \times 16 \]

Calculating \( 25 \times 16 \):

\[ 25 \times 16 = 400 \]

Now substituting this back into the formula:

\[ V = 3.14 \times 400 \]

Calculating \( 3.14 \times 400 \):

\[ V = 1256 \]

Thus, the volume of the peanut butter jar is 1,256 cubic centimeters. Therefore, the correct response is:

1,256 cubic centimeters.
