Final answer:
The volume of the cone is approximately 339.1 cm3.
Step-by-step explanation:
To find the volume of a cone, we use the formula V = (1/3) * π * r^2 * h, where r is the radius and h is the height. Since the diameter is given, we can find the radius by dividing the diameter by 2. In this case, the radius is 12/2 = 6 cm. Substituting the values into the formula, V = (1/3) * π * 6^2 * 9 = 108π ≈ 339.1 cm^3.
