Answer:
Approximately 38 cube inches of wax.
Step-by-step explanation:
The candle can be assumed to have the shape of a cylinder, so that;
volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h
where: r is the radius and h the height of the cylinder.
Thus,
volume of each candle = [tex]\pi[/tex][tex]r^{2}[/tex]h
But radius is 1 inch and height is 4 inches, then;
volume of each candle = [tex]\frac{22}{7}[/tex] x [tex]1^{2}[/tex] x 4
= [tex]\frac{22}{7}[/tex] x 1 x 4
= 12.5714
volume of each candle = 12.6 cube inches.
Therefore, for the three candles;
volume of the three candles = 3 x 12.5714
= 37.7142
volume of the three candles = 37.7142 cube inches
The amount of wax required for the three candles is approximately 38 cube inches.
