C Correct answer
Explanation

Volume = (1/3) * pi * r^2 * h = (1/3) * 3.14 * 4^2 * 9 = 3.14 * 16 * 3 = 150.72.

AI explanation

Using the formula for the volume of a cone, V = (1/3)πr²h, we substitute the given radius of 4 cm and height of 9 cm. This gives V = (1/3) × 3.14 × 4² × 9, which simplifies to 3.14 × 16 × 3. Multiplying these values results in 150.72, so the volume is 150.72 cubic centimeters.
