The area of a cirle is given by
[tex]A=\pi(R^2)\text{ where R is the radius, the distance from the edge/circumference to the centre}[/tex]We seek to find R, so let us make it the subject of the formula;
[tex]R=\sqrt[]{\frac{A}{\pi}}[/tex][tex]\begin{gathered} R=\sqrt[]{\frac{100}{3.142}} \\ R=5.64\approx6ft \end{gathered}[/tex]Therefore, the approximate distance from the edge of Frank's garden to the center of the garden is 6ft
