Answer: [tex]1272.51\ cm^3[/tex]
Step-by-step explanation:
Given
diameter of each candle is [tex]d=6\ cm[/tex]
The height of each candle is [tex]h=9\ cm[/tex]
The volume of a cylinder is [tex]V=\pi r^2h[/tex]
The volume of each candle is
[tex]\Rightarrow V=\pi \times 3^2\times 9\\\Rightarrow V=254.502\ cm^3[/tex]
For 5 candles it is
[tex]\Rightarrow 5V=1272.51\ cm^3[/tex]
Total wax used for 5 candles is [tex]1272.51\ cm^3[/tex]
