Stonehenge is an ancient megalithic site in southern England. Some believe it was designed to make astronomical observations, but archaeologists cannot agree on the reason that Stonehenge was constructed. Charcoal samples taken from a series of holes at Stonehenge have about 0.33 pounds of carbon-14 in a 06 pound sample. Estimate the age of the charcoal pits at Stonehenge Assume that the half-life of carbon-14 is 8333 years.
