What is the volume of a cone with a radius of 4 ft. and a height of 9 ft.? Let π=3.14
The formula to calculate the volume of a cone is V = (1/3)πr²h, where V is the volume, r is the radius, and h is the height.
Substituting the given values into the formula, we have:
V = (1/3)(3.14)(4²)(9)
V = (1/3)(3.14)(16)(9)
V = (1/3)(3.14)(144)
V ≈ (1/3)(452.16)
V ≈ 150.72
Therefore, the volume of the cone is approximately 150.72 cubic feet.
