To find the volume of the peanut butter jar, we can assume it is a cylinder, given that the dimensions provided are height and width (diameter). The formula for the volume \( V \) of a cylinder is:

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

Where:

  • \( \pi \) is a constant (3.14),
  • \( r \) is the radius of the cylinder,
  • \( h \) is the height of the cylinder.
  1. Calculate the radius: The width of the jar is given as 10 cm, which is the diameter. Therefore, the radius \( r \) is half the diameter: \[ r = \frac{\text{diameter}}{2} = \frac{10}{2} = 5 , \text{cm} \]

  2. Use the dimensions in the volume formula: The height \( h \) of the jar is 16 cm.

    Now plug the values into the formula: \[ V = 3.14 \times (5)^2 \times 16 \]

    Calculate \( (5)^2 \): \[ (5)^2 = 25 \]

    Now substitute back: \[ V = 3.14 \times 25 \times 16 \]

    Calculate \( 25 \times 16 \): \[ 25 \times 16 = 400 \]

    Now substitute: \[ V = 3.14 \times 400 \]

    Finally, calculate \( 3.14 \times 400 \): \[ V = 1256 , \text{cubic centimeters} \]

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