To find the volume of a jar shaped like a cylinder, you can use the formula:
\[ V = \pi r^2 h \]
where \( V \) is the volume, \( r \) is the radius, and \( h \) is the height.
- Find the radius: The width of the jar is given as 10 cm, which means the radius is half of that:
\[ r = \frac{10}{2} = 5 \text{ cm} \]
-
Use the height: The height of the jar is given as 16 cm.
-
Plug the values into the volume formula:
\[ V = 3.14 \times (5)^2 \times 16 \]
Calculating step-by-step:
- Calculate \( (5)^2 = 25 \).
- Then multiply by the height:
\[ 25 \times 16 = 400 \]
- Now multiply by \( \pi \):
\[ V = 3.14 \times 400 = 1256 \text{ cubic centimeters} \]
Thus, the volume of the peanut butter jar is 1,256 cubic centimeters.
