What is the area of a circle with a radius of 2.1 miles? Estimate the area to the hundreths place using 3.14 for π

Answer 1

The area of a circle is given by the formula:
A = π * r^2

Given:
r = 2.1 miles
π = 3.14

Substituting these values into the formula, we get:
A = 3.14 * (2.1)^2

Calculating,
A ≈ 3.14 * 4.41
A ≈ 13.8474

Rounding to the hundredths place, the estimated area of the circle is 13.85 square miles.
