To find the radius just divide the diameter by 2. (the radius is always half the diamter)
In which its:
15.7÷2≈ 7.85
It's a function because each input has one output
Y=kx+b
line is perpendicular y=1/3x+6⇒ k=-

=-3
so line y=-3x+a
this line that passes through (-9,12)⇔x=-9, y=12, so 12=-3(-9)+a
12=27+a
a=12-27
a=-15
y=-3x-15
