Answer:

135 ft^3

Step-by-step explanation:

The volume of a cone is [tex]\frac{1}{3} \pi r^{2}h[/tex]. The radius is 4 and the height is 8, so these values can be plugged in:

[tex]V = \frac{1}{3} \pi \times 4^{2} \times 8[/tex]

[tex]V = \frac{128\pi }{3}[/tex]

This is about 134.041286553 which rounds to 135 ft^3.
