To find the volume of a cylindrical jar, you can use the formula:

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

where \( V \) is the volume, \( r \) is the radius, and \( h \) is the height.

  1. The width of the jar is given as 10 centimeters, which means the diameter is 10 cm. The radius \( r \) is half of the diameter: \[ r = \frac{10}{2} = 5 \text{ cm} \]

  2. The height \( h \) of the jar is given as 16 centimeters.

  3. Now, substituting the values into the volume formula: \[ V = 3.14 \times (5)^2 \times 16 \]

  4. Calculate the radius squared: \[ (5)^2 = 25 \]

  5. Now substitute this back into the volume equation: \[ V = 3.14 \times 25 \times 16 \]

  6. First calculate \( 25 \times 16 \): \[ 25 \times 16 = 400 \]

  7. Now, multiply by \( \pi \): \[ V = 3.14 \times 400 \]

  8. Finally, calculate the volume: \[ V = 1,256 \text{ cubic centimeters} \]

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