The area of a cirle is given by

$A=\pi(R^2)\text{ where R is the radius, the distance from the edge/circumference to the centre}$

We seek to find R, so let us make it the subject of the formula;

$R=\sqrt[]{(A)/(\pi)}$
$\begin{gathered} R=\sqrt[]{(100)/(3.142)} \\ R=5.64\approx6ft \end{gathered}$

Therefore, the approximate distance from the edge of Frank's garden to the center of the garden is 6ft
