153.86 yd²

1) Since the area of a circle is found by this formula:


A\text{ =}\pi\cdot r^2

2) Let's plug into that the given information:


\begin{gathered} A\text{ =}\pi\cdot r^2 \\ A=3.14\cdot(7)^2 \\ A\text{ =3.14 }\cdot49 \\ A=153.86yd^2 \end{gathered}

3) Hence, the area of this circle is 153.86 yd²
