Hey there!☺

$Answer:\boxed{y=\frac{-1}{2}}$

$Explanation:$

$\frac{y}{-8}=\frac{1}{16}$

In our first step, we will use the cross multiply method:

$\frac{y}{-8}=\frac{1}{16}\\ y*(16)=(1)*(-8)\\16y=-8$

In our second/last step, we will divide both sides by 16:

$\frac{16y}{16}=\frac{-8}{16}\\y=\frac{-1}{2}$

Hope this helps!☺

C=(1/4)*circumference
Area=pq+3.142r^2
60*3.142=pq+3.142p^2
q=((1/4)*2p*3.142)+2*3.142
q=1.571p+6.284
188.52=1.571p^2+6.284p+3.142p^2
188.52=4.713p^2+6.284p
188520=4713p^2+6284p
