The radius of a circle is 3 kilometers. What is the circle's area?
Use 𝜋 ≈ 3.14 and round your answer to the nearest hundredth.
To find the area of a circle, you use the formula A = πr^2, where r is the radius of the circle.
Given that the radius, r, is 3 kilometers, we can plug in this value into the formula:
A = π(3)^2
A = π(9)
A ≈ 3.14 * 9
A ≈ 28.26
Therefore, the area of the circle is approximately 28.26 square kilometers.
