What is the area of a circle with a radius of 2.1 miles estimate the area to the hundredths place using 3.14 for π
The formula to calculate the area of a circle is A = πr^2, where A represents the area and r represents the radius of the circle.
Given that the radius is 2.1 miles and using 3.14 for π, we can calculate the area as follows:
A = 3.14 * (2.1)^2
A = 3.14 * 4.41
A ≈ 13.8164
Therefore, the area of the circle, rounded to the hundredths place, is approximately 13.82 square miles.
