To find the area of a circle, you can use the formula: A = πr², where:
- A is the area of the circle
- r is the radius of the circle
In this case, the radius (r) is 9 yards. So, we plug that value into the formula:
A = π(9)²
Calculating the square of the radius:
(9)² = 81
Now, substituting back into the formula gives us:
A = π * 81
Using the approximate value of π (pi) as 3.14, we can calculate:
A ≈ 3.14 * 81
Now, multiplying those values:
A ≈ 254.34
Therefore, the area of the circle with a radius of 9 yards is approximately 254.34 square yards.
This means that if you were to cover the entire area of this circle with material, it would require about 254.34 square yards of fabric or any other covering material.
