Homework Help: Algebra 1

Posted by Elizabeth on Thursday, January 17, 2008 at 7:18pm.

ok, no one has helped me with it the first time, let's see if this time is successful.

Jilian wants to buy candles in case her electricity and furnace fail. Each candle she plans to use, burns at a rate of 5mL of wax per 15 min. One of these candles has a diameter of 8 centimeters and a height of 15cm. How many HOURS wil it take the candle to burn down completely?
Express the answer to the NEAREST WHOLE NUMBER. (Note: 1 mL = 1 cm cubed) (Hint: A candle is a cylinder; use 3.14 as an estimate for pi.)
