Explanation:

Step1: Calculate radius from diameter

The diameter is 14 cm, so radius $r = \frac{14}{2} = 7$ cm.

Step2: Recall cone volume formula

The volume of a cone is $V = \frac{1}{3}\pi r^2 h$.

Step3: Substitute values into formula

Substitute $r=7$, $h=18$, $\pi=3.14$:
$$V = \frac{1}{3} \times 3.14 \times 7^2 \times 18$$

Step4: Compute step-by-step

First calculate $7^2=49$, then $49 \times 18=882$, next $\frac{1}{3} \times 882=294$, finally $294 \times 3.14=923.16$.

Answer:

923.16 cubic centimeters
