A cone has a radius of 4 feet on its base. The approximate volume of the cone is 189ft ^ 3 Determine the height of the cone to the nearest tenth of a foot. Use 3.14 for pi
(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 = pi * r ^ 2 * h
V = 1/3 * pi * r ^ 2 * h
V = 4/3 * pi * r ^ 3
A = pi * r ^ 2
B
189 = 64/3 pi h
189 = 16pi*h
189 = 8/3 * pi*h
189 = 16/3 pi h
C
23.6 = pi*h
504 = pi*h
1008 = pi*h
35.4 = pi*h
D
