The formula for the volume of a cylinder is given by:
Volume = π * radius^2 * height

In this case, the base radius is 8 inches and the height is 40 inches. Plugging these values into the formula, we get:
Volume = π * 8^2 * 40

Simplifying the expression, we have:
Volume = π * 64 * 40

Using a calculator to perform the multiplication, the volume is:
Volume ≈ 80,448.67 in^3

Therefore, the volume of the cylinder is approximately 80,448.67 cubic inches (rounded to two decimal places).

Apologies for the mistake. Let me correct the calculation.

The formula for the volume of a cylinder is given by:
Volume = π * radius^2 * height

In this case, the base radius is 8 inches and the height is 40 inches. Plugging these values into the formula, we get:
Volume = π * 8^2 * 40

Simplifying the expression, we have:
Volume = π * 64 * 40
Volume = 2560π

Using a calculator to evaluate π, the volume is approximately 8038.41 cubic inches.

Therefore, the volume of the cylinder is approximately 8038.41 cubic inches (rounded to two decimal places).

Simplifying the expression, we have:
Volume = π * 64 * 40
Volume = 2560π

Using a calculator to evaluate π, the volume is approximately 8028.53 cubic inches.

Therefore, the volume of the cylinder is approximately 8028.53 cubic inches (rounded to two decimal places).
