Question

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) JUST PUT THEE CORRECT RESPONCES IN THE RESPONCE AREA AS I HAVE THEM WRITEN
A. Use this formula: Responce Area

B. Substitute in for the radius and simplify to get Responce Area


C. Use the reciprocal to get about Responce Area


D. Use the inverse operation of Responce Area to get h by itself.

D. Height is approximately Responce Area

responce A:
V = 4/3 pi r^3
A = pi r^2
V = pi r^2 h
V= 1/3 pi r^2 h

responce B:
189 = 8/3 pi h
189 = 64/3 pi h
189 = 16/3 pi h
189 = 16 pi h

responce C:
1008 = pi h
504 = pi h
35.4 = pi h
23.6 = pi h

responce D:
subtraction
addition
multiplication
division

responce D:
8.2 ft
11.3 ft
2.5 ft
22.6 ft

Answer 1

responce A:
V = 1/3 π r² h

responce B:
189 = 1/3 * 3.14 * 4² * h
189 = 1/3 * 3.14 * 16 * h
189 = 16.76h

responce C:
h = 189 / 16.76
h ≈ 11.3

responce D:
h = 11.3 ft
