To find the area of a circle, you can use the formula A = πr^2, where A represents the area, π represents the mathematical constant pi, and r represents the radius of the circle.
Given that the radius of the circle is 2.1 miles and we are asked to estimate the area to the hundredth place using 3.14 for π, we can substitute the values into the formula and calculate the area.
First, square the radius: (2.1)^2 = 4.41.
Next, multiply this squared radius by π: 4.41 * 3.14 = 13.824.
Finally, round the result to the hundredth place: 13.824 rounds to 13.82.
Therefore, the estimated area of the circle with a radius of 2.1 miles is approximately 13.82 square miles.
