Answer:
615.8 m³
Explanation:
The formula for the volume of a cone is ...
V = (1/3)πr²h
For your given radius and height, the volume is ...
V = (1/3)π(14 m)²(3 m) = 196π m³
V ≈ 615.75216 m³ ≈ 615.8 m³
_____
The π button on the calculator uses a value slightly larger than 3.14, so an answer with 3.14 for pi will be incorrect.
