Question

A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 centimetres and a height of 2 centimetres. How much wax will the company need to make 270 candles?

Use 3.14 for π, and do not round your answer.

Answer 1

270 = 15,268.14030 in³

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 do not round your answer)?

Volume = π r² h __ 3.14 * 9 * 2 = 56.52 in³ * 270 = 15,260.4 in³

Using a typical ten digit calculator

3.141592654 * 9 * 2 = 56.54866777 in³ * 270 = 15,268.14030 in³ (rounded)

Answer 2

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
