Answer:
A. 27 π cubic inches
Step-by-step explanation:
The volume of a cylinder is calculated using the formula;
[tex]Volume=\pi r^2h[/tex]
From the given information, the smallest candle has a radius of 0.5 inches and a height of 3 inches.
We substitute [tex]r=0.5[/tex] and [tex]h=3[/tex] into the given formula.
The vlume of the smallest candle is
[tex]Volume=\pi \times0.5^2\times 3[/tex]
[tex]Volume=\frac{3}{4}\pi in^3[/tex]
from the given information, the other two candles are scaled versions of the smallest, with scale factors of 2 and 3.
The volume of the other two candles will be [tex]2^3\times \frac{3}{4}\pi=6\pi in^3[/tex] and [tex]3^3\times \frac{3}{4}\pi=\frac{81}{4}\pi in^3[/tex]
The wax needed to create one set of candle is
[tex]\frac{3}{4}\pi+6\pi+\frac{81}{4}\pi=27\pi\: in^3[/tex]
The correct answer is A
