The correct answer is 423.9 cubic inches.

To calculate the volume of a cone, you can use the formula V = (1/3)πr^2h, where r is the radius of the base and h is the perpendicular height from the apex to the base.

Plugging in the values given:
V = (1/3) * 3.14 * 9^2 * 5
V = (1/3) * 3.14 * 81 * 5
V = (1/3) * 3.14 * 405
V ≈ 423.9

Therefore, the volume of the cone is approximately 423.9 cubic inches.
