Question

The radius of a circle is 2 miles. What is the circle's area?

Answer 1

Answer: 12.5664 Mi^2

Explanation:

Circle area = π * r² = π * 4 [inch²] ≈ 12.566 [in²]

π ≈ 3.14159265 ≈ 3.14

d = r * 2 = 2 [inch] * 2 = 4 [inch]

Answer 2

4π square miles.

Explanation:

The area of a circle is given by the formula A = πr², where A is the area and r is the radius.

Substituting r = 2 miles, we get:

A = π(2 miles)² = 4π square miles
