For this case we have that by definition, the volume of a cone is given by:

$V = \frac {1} {3} \pi * r ^ 2 * h$

Where:

A: It's the radio

h: It's the height

We have by the statement of the problem that:

$r = 9 \ units\\h = 8 \ units$

Substituting:

$V = \frac {1} {3} \pi * r ^2 * h\\V = \frac {1} {3} \pi * 9 ^ 2 * 8\\V = \frac {1} {3} \pi * 81 * 8\\V = \frac {1} {3} \pi * 648\\V = 216 \pi$

Answer:

$216 \pi \ units ^ 3$
