Chapter 14, Problem 39AP
In 1983, the United States began coining the one-cent piece out of copper-clad zinc rather than pure copper. The mass of the old copper penny is 3.083 g and that of the new cent is 2.517 g. The density of copper is 8.920 g/cm3 and that of zinc is 7.133 g/cm3. The new and old coins have the same volume. Calculate the percent of zinc (by volume) in the new cent.

Every day, Jill collects one full bucket of water from the well up the hill. The well has a diameter of 0.800 m and a depth of 3.00 m. Currently, only 65.3% of the well is full. If Jill collects one full bucket every day from today, and it takes her 851 days to empty the well, how many pints of water was she collecting per trip?
1 qt = 2 pints, 1 L = 1.06 qt, 1 m3 = 1000 L, V = πr2h
