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.
E. Height is approximately ____
A. V = 1/3πr^2h
B. 189 = 1/3 * 3.14 * 16 * h
189 = 6.28 * h
h = 189 / 6.28
C. h ≈ 30.1 feet
D. Division
E. Height is approximately 30.1 feet.
