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

Question

.

Answer 1

The area of a circle is given by the formula A = πr^2, where A is the area and r is the radius.

Plugging in the given radius of 2.1 miles and using 3.14 for π, we have A = 3.14 * (2.1)^2.
Simplifying, we get A = 3.14 * 4.41 = 13.8434.

Rounding to the hundredths place, we have an estimated area of 13.84 square miles.
