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, and \( h \) is the height.
Given:
- Radius \( r = 8 \) ft
- Height \( h = 20 \) ft
Now, substitute the values into the formula using \( \pi \approx 3.14 \):
\[
V = 3.14 \times (8)^2 \times 20
\]
Calculating \( (8)^2 \):
\[
(8)^2 = 64
\]
Now substitute this back into the equation:
\[
V = 3.14 \times 64 \times 20
\]
Now, calculate \( 64 \times 20 \):
\[
64 \times 20 = 1280
\]
Now substitute this back into the volume equation:
\[
V = 3.14 \times 1280
\]
Finally, perform the multiplication:
\[
V = 4019.2
\]
Thus, the volume of the cylinder is:
\[
\boxed{4019.2} \text{ cubic feet}
\]
\[
