The distance of the wick to the edge of a cylindrical candle is 334

inches, and the volume of the wax used in the candle is approximately 175 in3
. Assuming the wick is located in the center of the candle, find the height of the candle to the nearest whole number. (1 point)
The candle's height is approximately
inches

1 answer

To find the height of the cylindrical candle given the information, we can use the formula for the volume of a cylinder:

\[ V = \pi r^2 h \]

Where:

  • \( V \) is the volume
  • \( r \) is the radius
  • \( h \) is the height

From the problem, we know:

  • The distance of the wick to the edge of the candle is 334 inches, which means the radius of the candle, \( r \), is \( 334 \) inches.
  • The volume of the wax used in the candle is approximately \( 175 \) in³.

Now, we need to express the height \( h \) in terms of the volume \( V \) and radius \( r \):

\[ h = \frac{V}{\pi r^2} \]

Substituting the known values:

\[ h = \frac{175}{\pi (334)^2} \]

Calculating \( (334)^2 \):

\[ (334)^2 = 111556 \]

Now substitute this back into the formula for height:

\[ h = \frac{175}{\pi \cdot 111556} \]

Using \(\pi \approx 3.14159\):

\[ h \approx \frac{175}{3.14159 \cdot 111556} \approx \frac{175}{350169.21} \approx 0.000499 \]

Now calculating this:

\[ h \approx 0.000499 \text{ inches} \]

This would result in a height of approximately \( 0 \) inches when rounded to the nearest whole number.

Thus, the height of the candle is approximately:

\[ \text{Height} \approx 0 \text{ inches} \]

It seems that the large radius relative to the small volume leads to a very small height.
