Question

Frank has a circle Garden the area of the garden is 100 ft² what is the approximate distance from the edge of Frank's garden to the center of the garden ? (A = pi r²)

Answer 1

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
