Answer:
270 = 15,268.14030 in³
Step-by-step explanation:
A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 inches and a height of 2 inches. How much wax will the company need to make 270 (use 3.14 for n, and <u>do not</u> round your answer)?
Volume = π r² h __ 3.14 * 9 * 2 = 56.52 in³ * 270 = 15,260.4 in³
Using a <em>typical</em> ten digit calculator
3.141592654 * 9 * 2 = 56.54866777 in³ * 270 = 15,268.14030 in³ (<em>rounded</em>)
Volume of cylinder = pi x r^2 x height
Volume = 3.14 x 3^2 x 2 = 56.52 cubic cm.
Multiply the volume of a cylinder by total candles:
56.52 x 270 = 15,260.4 cubic cm
