To find the volume of a cylindrical rain barrel, you can use the formula for the volume of a cylinder:

\[ V = \pi r^2 h \]

Where:

  • \(V\) is the volume,
  • \(r\) is the radius of the base,
  • \(h\) is the height of the cylinder.

Given:

  • The height (\(h\)) is 37 inches,
  • The diameter is 22 inches, so the radius (\(r\)) is half of the diameter:

\[ r = \frac{diameter}{2} = \frac{22}{2} = 11 \text{ inches} \]

Now we can plug the values into the volume formula:

\[ V = \pi (11)^2 (37) \] \[ V = \pi (121) (37) \] \[ V = \pi (4477) \] \[ V \approx 3.14 \times 4477 \approx 14,052.58 \text{ cubic inches} \]

Choosing from the provided options, the closest to this calculation is:

14,057.78 inches³

Therefore, the volume of Hondo's rain barrel is approximately 14,057.78 cubic inches.
