Chapter 12.3, Problem 14PPS

To determine

To calculate: Volume of candle.

Answer to Problem 14PPS

Volume $\left(V\right)$ of the scented candle is $77in$ .

Explanation of Solution

Given:

A scented candle is in the shape of cylinder that means

Height $\left(H\right)$ of the cylinder $=8in$

Diameter of the candle $=3.5in$

Radius of cylinder base $\left(r\right)=\frac{d}{2}=\frac{3.5}{2}=1.75inch$

Calculation:

The formula for the volume of candle can be calculated as,

  $V=\pi r^{2}h$

After putting the values in the equation,

  $V=\pi {\left(r\right)}^2\left(h\right)$

  $V=3.14\times {\left(1.75\right)}^2\left(8\right)$

  $\begin{array}{l}V=\frac{539}{7}\\ V=76.93\simeq 77in\end{array}$

Thus, Volume $\left(V\right)$ of the scented candle is $77in$ .
