The radius of a circle is 3 miles. What is the circle's area?
Use 3.14 for 𝜋.
The area of the circle is:
𝐴 = 𝜋𝑟²
𝐴 = 3.14(3)²
𝐴 = 3.14(9)
𝐴 = 28.26 square miles
Therefore, the area of the circle with a radius of 3 miles is 28.26 square miles.
To calculate the area of a circle, you can use the formula:
Area = 𝜋 * radius^2
Given that the radius of the circle is 3 miles, we can substitute the value into the formula:
Area = 3.14 * (3 miles)^2
Area = 3.14 * 9 square miles
Area = 28.26 square miles
Therefore, the area of the circle is 28.26 square miles.
