Use the image to answer the question.
An oblique cone shows a base radius of 9 inches. The perpendicular height is 5 inches from the apex to the base outside the cone. A right angle is formed outside the cone to the right. A dashed diagonal line connects the center of the circular base to the apex.

To find 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.
In this case, the base radius is given as 9 inches and the perpendicular height is 5 inches.
So, the volume of the cone is V = (1/3)π(9^2)(5) = (1/3)π(81)(5) = (1/3)(405π) = 135π ≈ 423.9 cubic inches.
Therefore, the correct answer is 423.9 cubic inches.
