The dartboard in the picture is made up of three concentric circles with radii \( 4 \), \( 6 \) and \( 8 \) cm. Assuming that a dart thrown will land randomly on the dartboard, what is the probability that it lands in the red region?
\( \frac5{16}\doteq 0{.}3125 \)
\( \frac3{4}=0{.}75 \)
\( \frac1{4}=0{.}25 \)
\( \frac9{16}\doteq 0{.}5625 \)
