To find the volume of the peanut butter jar, we first note that it can be approximated as a cylinder. The formula for the volume \( V \) of a cylinder is:

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

where:

  • \( r \) is the radius of the base,
  • \( h \) is the height,
  • \( \pi \) is a constant approximately equal to 3.14.

Given:

  • Height \( h = 16 \) cm,
  • Width (diameter) = 10 cm, so the radius \( r = \frac{10}{2} = 5 \) cm.

Now, we can substitute these values into the volume formula:

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

Calculating \( r^2 \):

\[ (5)^2 = 25 \]

Now substituting that back into our volume equation:

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

Calculating \( 25 \times 16 \):

\[ 25 \times 16 = 400 \]

Now substituting this value into the equation:

\[ V = 3.14 \times 400 \]

Calculating \( 3.14 \times 400 \):

\[ V = 1256 \]

Thus, the volume of the peanut butter jar is:

\[ \boxed{1256} \text{ cubic centimeters} \]

So, the correct response is 1,256 cubic centimeters.
