Answer:

184.9 ft³

Explanation:

In order to find the volume, we need to know the radius. We can find that from the circumference.

C = 2πr

r = C/(2π) = 29.516/(6.28319) ≈ 4.6976 . . . . feet

The volume of the cone is found using the formula ...

V = 1/3πr²h

V = 1/3π(4.6976 ft)²(8 ft) ≈ 58.847π ft³

V ≈ 184.9 ft³ . . . . volume of the cone

_____

The "pi button" is used throughout. If you use 3.14 for pi, your answer may be closer to 185.0 (rounded to tenths).
