so, the smallest candle has a radius r = 0.5 and a height of h = 3.
now, the other two candles in the set, are scaled of 2(twice as large) and of 3(thrice as large).
therefore, the candle scaled at 2 has a radius of 2*0.5 or 1, and a height of 2*3 or 6.
and the last candle in the set scaled t 3 has a radius of 3*0.5 or 1.5, and a height of 3*3, or 9
