376.8 cubic centimeter of wax are needed for the candle.
Solution:
Radius of the cylinder = 2 cm
Height of the cylinder = 30 cm
The value of π = 3.14
To find how much wax are needed to make the candle:
Volume of the cylinder = [tex]\pi r^2 h[/tex]
= 3.14 × 2² × 30
Volume of the cylinder = 376.8 cubic centimeter
Hence 376.8 cubic centimeter of wax are needed for the candle.
