The smallest candle has a radius of 0.5 inches and a height of 3 inches. the other two candles are scaled versions of the smallest, with scale factors of 2 and 3. how much wax is needed to create one set of candles?

Volume of smallest candle = pi r^2 h =  pi*0.5^2 * 3 = 2.356 ins^3

volume of  candle with scale factor 2 = 2.356 * 2^3 = 18.848

3 = 2.356 * 3^3 = 63.612

Total volume of wax needed =   2.356 + 18,848 + 63.612 =  84.816

Answer is 84.82 ins^3  of wax to the nearest hundredth.
