To find the volume of a cylinder, you can use the formula:
\[ V = \pi r^2 h \]
where \( V \) is the volume, \( r \) is the radius of the base, and \( h \) is the height.
Given:
- Radius \( r = 4 \) meters
- Height \( h = 7 \) meters
- Using \( \pi \approx 3.14 \)
Now, plug the values into the formula:
\[ V = 3.14 \times (4^2) \times 7 \]
First, calculate \( 4^2 \):
\[ 4^2 = 16 \]
Now multiply that by the height:
\[ 16 \times 7 = 112 \]
Now multiply by \( \pi \):
\[ V = 3.14 \times 112 \]
Calculating that gives:
\[ V = 351.68 \]
Thus, the volume of the cylinder is approximately:
\[ \boxed{351.68} \text{ cubic meters} \]
