A cone has a radius of 4 feet on its base. The approximate volume of the

Question

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 _____

Answer 1

A. Use this formula: V = (1/3)πr^2h
B. Substitute in for the radius and simplify to get 189 = (1/3)(3.14)(4^2)h = 16.72h
C. Use the reciprocal to get about h = 189 / 16.72 ≈ 11.3
D. Use the inverse operation of multiplication to get h by itself.
E. Height is approximately 11.3 feet.
