Question

he Candle Factory is producing a new candle. It has a radius of 3 inches and a height of 5 inches. How much wax is needed to make the candle? Use 3.14 for Pi. Round to the nearest whole cubic inch.

A cylinder with a radius of 3 inches and height of 5 inches.

Recall the formulas S A = 2 pi r squared + 2 pi r h and V = pi r squared h.

Answer 1

QuestioN :

The Candle Factory is producing a new candle. It has a radius of 3 inches and a height of 5 inches. How much wax is needed to make the candle? Use 3.14 for π. Round to the nearest whole cubic inch.

GiveN :

• Radius of candle (r) = 3 inches
• Height of candle (h) = 5 inches

To FinD :

• How much wax is used to make a candle

SolutioN :

We are given with radius and height of the candle,and we have to find how much wax is required to make a candle. So, here we have to simply find out the volume of cylindrical Cylinder in inches³

$\underbrace{\sf{Volume \: of \: Wax \: Used}}$

$\implies \sf{V \: = \: \pi r^2 h} \\ \\ \implies \sf{V \: = \: 3.14 \: \times \: 3^2 \: \times \: 5} \\ \\ \implies \sf{V \: = \: 3.14 \: \times \: 9 \: \times \: 5} \\ \\ \implies \sf{V \: = \: 3.14 \: \times \: 45} \\ \\ \implies \sf{V \: = \: 141.3} \\ \\ \underline{\sf{\therefore \: 141.3 \: inches^3 \: wax \: is \: used \: to \: make \: a \: candle}}$
