Given:

Radius of the dartboard is 12in.

Each side of the shaded region is 4in.


\begin{gathered} \text{Total area of the circle=}\pi(r^2) \\ =3.14*12*12 \\ =452.16in^2 \end{gathered}
\begin{gathered} \text{Area of the shaded region=4}*4 \\ =16in^2 \end{gathered}
\begin{gathered} Probability\text{ that dart lands in the shaded region=}(16)/(452.16) \\ =0.04 \end{gathered}
