Answer:

A

Step-by-step explanation:

The volume of the cone is found using the volume formula for a cone [tex]V=\frac{1}{3}\pi r^2h[/tex].

Substitute h=8 and r = 12.

[tex]V = \frac{1}{3}\pi r^2h\\V = \frac{1}{3}\pi (12^2)(8)\\V=\frac{1}{3}\pi *144*8\\V = \frac{1152}{3}\pi \\V= 384\pi \\V=1,205.76[/tex]

So the volume is approximately 1,206 cubic cm.
