To calculate the area of a circle using the formula \( A = \pi r^2 \), where \( r \) is the radius, you can plug in the value of the radius.
In this case, the radius \( r \) is 5 yards.
Now, substitute the value of \( r \) into the formula:
\[
A = \pi (5)^2
\]
\[
A = \pi (25)
\]
\[
A = 25\pi
\]
Using \( \pi \approx 3.14 \), you can approximate the area:
\[
A \approx 25 \times 3.14 = 78.5 \text{ square yards}
\]
Thus, the area of the circle is approximately \( 78.5 \) square yards. If you prefer an exact answer, you can simply state the area as \( 25\pi \) square yards.
