Y=(x+9)(x-3)+c
∵(-3,-36)lies on it.
-36=(-3+9)(-3-3)+c
-36=(-6)(-6)+c
-36=36+c
c=-36-36=-72
y=(x-9)(x+3)-72
y=x^2+3x-9x-27-72
y=x^2-6x-99

r = $\frac{84.78}{2 \pi}\\$ ≈ 13.493 mm

Step-by-step explanation:

The formula for the circumference c of a circle is

$c = 2 * \pi * r$ ,

where r is the radius.

Dividing both sides of the equation gives

$\frac{c}{2 \pi} = r$ .

Plugging in c = 84.78 gives you the Answer.
