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,
- \( h \) is the height.
Given:
- \( r = 4 \) meters
- \( h = 7 \) meters
- We'll use \( \pi \approx 3.14 \)
Now, substitute the values into the formula:
\[ V = 3.14 \times (4)^2 \times 7 \]
Calculate \( (4)^2 \):
\[ (4)^2 = 16 \]
Now substitute back into the formula:
\[ V = 3.14 \times 16 \times 7 \]
Now calculate \( 16 \times 7 \):
\[ 16 \times 7 = 112 \]
Now substitute back into the equation:
\[ V = 3.14 \times 112 \]
Now calculate \( 3.14 \times 112 \):
\[ V \approx 351.68 \]
Finally, rounding to the nearest hundredth:
The volume of the cylinder is approximately 351.68 cubic meters.
