To find the volume of the peanut butter jar, we first assume the jar is cylindrical. The formula for the volume \( V \) of a cylinder is:
\[ V = \pi r^2 h \]
where:
- \( r \) is the radius
- \( h \) is the height
- \( \pi \) is approximately 3.14
Given the width (or diameter) of the jar is 10 cm, the radius \( r \) is half of that:
\[ r = \frac{10}{2} = 5 \text{ cm} \]
The height \( h \) is given as 16 cm. Now we can plug these values into the volume formula:
\[ V = 3.14 \times (5^2) \times 16 \]
Calculating \( 5^2 \):
\[ 5^2 = 25 \]
Now substituting into the volume formula:
\[ V = 3.14 \times 25 \times 16 \]
Calculating \( 25 \times 16 \):
\[ 25 \times 16 = 400 \]
Now substituting back:
\[ V = 3.14 \times 400 \]
Finally, multiplying:
\[ V = 1256 \text{ cubic centimeters} \]
Therefore, the volume of the peanut butter jar is:
1,256 cubic centimeters
