The formula for the area of the circle is;
[tex]A=\pi(R)^2[/tex]We are given the diameter, which is 14yd, we need to obtain the radius R. We know that;
[tex]\text{Radius}=\frac{Diameter}{2}[/tex]So,
[tex]R=\frac{14}{2}=7yd[/tex]Therefore, the area is;
[tex]A=\frac{22}{7}\times7\times7=154yd^2[/tex]Therefore, the area of the circle is 154 square yards.
