Estimate the answer by rounding each number to one nonzero digit first, then perform the actual calculation. In 2005 , there were 3.318 million square kilometers of rainforest in a certain country. Each year, approximately 0.012 million square kilometer is lost to deforestation and development. By 2016 , how many square kilometers of rainforest remained? Estimate. Do not round the years, 2005 and 2016 . In 2016 , the area of rainlorest will be about (Type a whole number or a decimal.)

To estimate the area of rainforest remaining in 2016, we first round the numbers involved. 1. **Initial area of rainforest in 2005**: - 3.318 million square kilometers rounds to **3 million square kilometers**. 2. **Annual loss due to deforestation**: - 0.012 million square kilometers rounds to **0.01 million square kilometers**. 3. **Number of years from 2005 to 2016**: - This is 11 years (2016 - 2005). Now, we can calculate the estimated total loss over 11 years: \[ \text{Total loss} = \text{Annual loss} \times \text{Number of years} = 0.01 \text{ million} \times 11 = 0.11 \text{ million square kilometers} \] Next, we subtract the estimated total loss from the initial area: \[ \text{Remaining area} = \text{Initial area} - \text{Total loss} = 3 \text{ million} - 0.11 \text{ million} = 2.89 \text{ million square kilometers} \] Now, converting this back to a whole number: \[ 2.89 \text{ million square kilometers} = 2,890,000 \text{ square kilometers} \] Thus, the estimated area of rainforest remaining in 2016 is approximately **2,890,000 square kilometers**.
