<span>To find out how much wax is needed for the candles we need to figure out the volume of each candle. We know radius r=0.5 inches and height h=3 inches of the smallest candle and we know that the middle candle has r2=2r=1 inch and h2=2h=6 inches and the biggest candle has r3=3r=1.5 inches and h3=3h=9 inches. So now we need the formula for volume: V=pi*r^2*h and we simply plug in the numbers. First candle is V=3.14*(0.5^2)*3=2.355 inches^3. Middle candle: V2=3.14*(1^2)*6=18.84 inches^3. Biggest candle: V3=3.14*(1.5^2)*9=63.585 inches^3. So overall wax needed to create all three candles is V+V2+V3=2.355 inches^3 + 18.84 inches^3 + 63.585 inches^3=84.78 inches^3.</span>

I believe the answer is A
You start off with 400 and then you divide that by 30. 400/30= 13.3
this is your answer
Question does not make sense.
The percentage increase in the value of the necklace is 66.6%.
Given that
- In the year 2019, the necklace sold for $11,818,500.
- And, in the year 2000, the necklace sold for $7,096,000.
Based on the above information, the percentage increase in the value of the necklace is
= ($11,818,500 - $7,096,000) ÷ $7,096,000
= 66.6%
Therefore we can conclude that the percentage increase in the value of the necklace is 66.6%.
