To find the volume of a cone, you can use the formula:
V = (1/3) * π * r^2 * h
where:
V = volume of the cone
π ≈ 3.14
r = base radius of the cone
h = perpendicular height of the cone
In this case:
r = 9 inches
h = 5 inches
V = (1/3) * 3.14 * 9^2 * 5
V = (1/3) * 3.14 * 81 * 5
V = (1/3) * 3.14 * 405
V = 3.14 * 135
V = 424.5 cubic inches
Therefore, the volume of the cone is 424.5 cubic inches.
