Chapter 12, Problem 7PT

To determine

To find the volume of the candle.

Answer to Problem 7PT

The volume of the candle $=36.926$ Cubic. Inches

Explanation of Solution

Given information:

A circular pillar candle is $2.8$ inches wide and 6 inches tall.

Formula used:

Volume of cylinder:

The volume of cylinder is the density of the cylinder which signifies the amount of material it can carry. It is given by the formula:

$V=\pi r^{2}h$ , where r is the radius of the circular base and h is the height of the cylinder.

From the given information:

Height of the candle, $h=6$ inches

Radius of circular base, $r=\frac{2.8}{2}=1.4$ inches

∴ Volume of candle, $V=\pi r^{2}h$

$=\pi \cdot {\left(1.4\right)}^2\cdot 6$

$=\left(3.14\right)\cdot \left(6.16\right)\cdot 6$

$=36.926$ Cubic. Inches
