The formula for the area of a circle is
[tex]A=\pi\cdot r^2[/tex]solve the equation for the radius
[tex]\begin{gathered} A=\pi\cdot r^2 \\ \frac{A}{\pi}=r^2 \\ r=\sqrt[]{\frac{A}{\pi}} \end{gathered}[/tex]Replace the information given into the formula
[tex]\begin{gathered} r=\sqrt[]{\frac{67.3}{\pi}} \\ r\cong4.63 \end{gathered}[/tex]The radius of the garden is approximately 4.63 yards.
