Question

You want to make and sell three different sizes of cylindrical candles. You buy 1 cubic foot of candle wax for $20 to make 8 candles of each size.

a. Design the candles . What are the dimensions of each size of candle ?

Answer 1

Step 1: Let us assume

Radius of candle 1 = 7 foot , height of candle 1 = 7 foot

Radius of candle 1 = 14 foot , height of candle 1 = 14 foot

Radius of candle 1 = 21 foot , height of candle 1 = 21 foot
Step 2:

Volume of candle $l=\mathrm{\pi }{\left(\mathrm{l}\right)}^2\mathrm{l}=3.141\mathrm{cubic}\mathrm{ft}$

Volume of 8 candles =$=3.141*8=25.125ft$

Volume of candle
