A. Use this formula: V = 1/3 π r^2 h
B. Substitute in for the radius and simplify to get 189 = 1/3 * 3.14 * 4^2 * h
C. Simplify to get 189 = 1/3 * 3.14 * 16 * h
D. Multiply and simplify to get 189 = 16.75 h
E. Divide by 16.75 to solve for h and get h ≈ 11.3 ft
Therefore, the height of the cone is approximately 11.3 feet.
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: V = 1/3 pi r^2 h
B. Substitute in for the radius and simplify to get 189 = 16 pi h
C. Use the reciprocal to get about ( please help what the reciprocal would be
