Answer
$\frac{10.2}{\sqrt \pi}$ inches
Work Step by Step
We are given that the radius of a circle of area A is given by the function $r=\sqrt (\frac{A}{\pi})$. Furthermore, we are given that the area of the circle is 104 square inches.
Therefore, $r=\sqrt (\frac{104}{\pi})=\frac{\sqrt 104}{\sqrt \pi}=\frac{10.2}{\sqrt \pi}$ inches.
