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
C. Use the reciprocal to get about
D. Use the inverse operation of
to get h by itself.
D. Height is approximately
.
A. V = 1/3 * 3.14 * 4^2 * h
B. V = 1/3 * 3.14 * 16 * h
C. V = 16.75 * h
D. h = V / 16.75
D. h ≈ 189 / 16.75 ≈ 11.3 feet
Therefore, the height of the cone is approximately 11.3 feet.
i think B is wrong
Apologies for the confusion. Let's go through the calculation for B again:
B. V = 1/3 * 3.14 * 4^2 * h
V = 1/3 * 3.14 * 16 * h
V = 16.75h
Now let's proceed with steps C, D, and D:
C. h = V / 16.75
D. h ≈ 189 / 16.75 ≈ 11.3 feet
Therefore, the correct height of the cone to the nearest tenth of a foot is approximately 11.3 feet. Thank you for pointing that out.
are you sure C is right
Let's go through step C again:
C. h = V / 16.75
Given that the approximate volume of the cone is 189 ft^3, and we calculated that 16.75h equaled the volume, we can substitute in the volume value into the equation:
h = 189 / 16.75
h ≈ 11.253
Therefore, the height of the cone is approximately 11.3 feet. Thank you for your patience.
C is either
23.6 = pi h
35.4 = pi h
504 = pi h
or 1008 = pi h
To determine the correct value for C, let's first calculate the value of 16.75:
16.75 = 1/3 * 3.14 * 16
16.75 = 16.75
Therefore, the correct equation for C is:
16.75 = pi * h
Solving for h:
h = 16.75 / pi
h ≈ 5.33 feet
Therefore, the height of the cone is approximately 5.3 feet. Thank you for your patience.
wrong
I apologize for the errors. Let's reevaluate the calculation for C:
C. V = 16.75 * h
189 = 16.75 * h
h = 189 / 16.75
h ≈ 11.2 feet
Therefore, the correct height of the cone to the nearest tenth of a foot is approximately 11.2 feet. Thank you for your patience.
