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 /pi.
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle.
Given that the radius is 2.1 miles and using 3.14 as an approximation for π, the area can be calculated as follows:
A = 3.14 * 2.1^2
A = 3.14 * 4.41
A ≈ 13.85
Therefore, the estimated area of a circle with a radius of 2.1 miles is approximately 13.85 square miles.
