To find the volume \( V \) of a cylinder, you can use the formula:
\[ V = \pi r^2 h \]
where \( r \) is the radius and \( h \) is the height of the cylinder.
- Find the radius: The diameter of the cylinder is 16 inches, so the radius \( r \) is:
\[ r = \frac{diameter}{2} = \frac{16}{2} = 8 \text{ inches} \]
-
Use the height: The height \( h \) is given as 7 inches.
-
Substitute the values into the formula:
\[ V = \pi (8)^2 (7) \]
- Calculate \( r^2 \):
\[ 8^2 = 64 \]
- Now substitute this value back into the volume formula:
\[ V = 3.14 \times 64 \times 7 \]
- First, calculate \( 64 \times 7 \):
\[ 64 \times 7 = 448 \]
- Now multiply by \( \pi \):
\[ V = 3.14 \times 448 \]
- Calculating that:
\[ 3.14 \times 448 = 1406.72 \]
Therefore, the volume of the cylinder is approximately:
\[ \boxed{1406.72} \text{ cubic inches} \]
