A cone has a radius of 4 feet on its base. The approximate volume of the cone is 189 ft^3. Determine the height of the cone to the nearest tenth of a foot. Use 3.14 for π.(5 points) A. Use this formula: V = 1/3 pi r^2 h B. Substitute in for the radius and simplify to get C. Use the reciprocal to get about D. Use the inverse operation of to get h by itself. D. Height is approximately .
A. V = 1/3 * 3.14 * 4^2 * h
B. V = 1/3 * 3.14 * 16 * h
V = 16.75h
C. h = V / 16.75
h ≈ 11.27
D. Height is approximately 11.3 feet.
