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

Question

(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
