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: 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)πr^2h
B. 189 = (1/3)(3.14)(4^2)h
189 = (1/3)(3.14)(16)h
189 = 16.7472h
C. h = 189 / 16.7472
h ≈ 11.27
D. Height is approximately 11.3 feet.
