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

In the case of the peanut butter jar:

  • The width is 10 centimeters, so the radius \( r \) is half of that: \( r = 10 / 2 = 5 \) centimeters.
  • The height \( h \) is 16 centimeters.

Now, plug the values into the volume formula:

\[ V = 3.14 \times (5^2) \times 16 \] \[ V = 3.14 \times 25 \times 16 \] \[ V = 3.14 \times 400 \] \[ V = 1256 \text{ cubic centimeters} \]

So, the volume of the peanut butter jar is 1,256 cubic centimeters.
