The formula for calculating the area of a circle is A = πr^2, where r is the radius of the circle.
Given that the radius of the circle is 2.1 miles and using the value of π as 3.14, we can calculate the area as:
A = 3.14 * (2.1)^2
A = 3.14 * 4.41
A = 13.8534
Rounding to the hundredths place, the area of the circle with a radius of 2.1 miles is approximately 13.85 square miles.
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
