Question

A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 inches and a height of 6 inches. How much wax will the company need to make 110 candles?
Use 3.14 for pie , and do not round your answer.

Answer 1

If each candle has a diameter of 6 inches, hence it is radius is 3 inches.

The height given is 6 inches.

Now, we need to find the volume of one candle.

The volume of a cylinder is given by:

$V=\pi r^2h$

Replacing using the given values:

$\begin{gathered} V=(3.14)(3in)^2(6in) \\ V=169.56in^3 \end{gathered}$

Now, we multiply 110 candles by 169.56 in³.

Hence, the result is:

= 18651.6in³
