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.
What is the volume of the cone? Use 3.14 for pi.

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.
