Estimate the answer by rounding each number to one nonzero digit first, then perform the actual calculation. In 2005 , there were 3.418 million square kilometers of rainforest in a certain country. Each year, approximately 0.013 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 rainforest will be about \( \square \) million square kilometers. (Type a whole number or a decimal.)

To estimate the answer, we will first round each number to one nonzero digit and then perform the actual calculation. Given: - In 2005, there were 3.418 million square kilometers of rainforest. - Each year, approximately 0.013 million square kilometers is lost to deforestation and development. Let's calculate the number of years from 2005 to 2016: 2016 - 2005 = 11 years Now, let's calculate the total loss of rainforest from 2005 to 2016: Total loss = 0.013 million square kilometers/year * 11 years Next, we will subtract the total loss from the initial amount of rainforest in 2005 to find the remaining area of rainforest in 2016. Let's perform the calculations step by step. Calculate the value by following steps: - step0: Calculate: \(0.013\times 11\) - step1: Multiply the numbers: \(0.143\) The total loss of rainforest from 2005 to 2016 is 0.143 million square kilometers. Now, let's calculate the remaining area of rainforest in 2016 by subtracting the total loss from the initial amount of rainforest in 2005. Calculate the value by following steps: - step0: Calculate: \(3.418-0.143\) - step1: Subtract the numbers: \(3.275\) The remaining area of rainforest in 2016 is approximately 3.275 million square kilometers. Therefore, the estimated area of rainforest in 2016 is 3.275 million square kilometers.
