To find the area of Fiona’s circle, we can use the formula for the area of a circle, which is:
Area = π × r²
In this formula, r is the radius of the circle. Since Fiona’s circle has a diameter of 14 meters, we first need to find the radius. The radius is half of the diameter:
Radius (r) = Diameter / 2 = 14 meters / 2 = 7 meters
Now that we have the radius, we can plug it into the area formula:
Area = π × (7 meters)²
This simplifies to:
Area = π × 49 square meters
Using the approximate value of π (3.14), we can calculate:
Area ≈ 3.14 × 49 ≈ 153.86 square meters
Therefore, the area of Fiona’s circle is approximately 153.86 square meters.
