Explanation:

Step1: Find the radius

The diameter is 14.4 ft, so the radius \( r = \frac{14.4}{2} = 7.2 \) ft.

Step2: Recall the volume formula for a cone

The volume \( V \) of a right circular cone is given by \( V = \frac{1}{3}\pi r^2 h \), where \( h \) is the height.

Step3: Substitute the values

Here, \( r = 7.2 \) ft and \( h = 2.7 \) ft. So,
