$C=2 \pi R \\ \\ C=16ft \\ \\ 2\pi R=16 = \boxed{R=\frac{16}{2\pi}=\frac{8}{\pi}} \\ \\ R=\frac{8}{\pi}=\frac{8}{3.14} \\ \\\boxed{\boxed{R \approx 2.5}}$

$The\ circumference\ of\ a\ circle:C=2\pi r\ \ \ \ (r-radius)\\\\C=16ft\\\\2\pi r=16\ \ \ \ \ \ |divide\ both\ sides\ by\ 2\pi\\\\r=\frac{16}{2\pi}\\\\r=\frac{8}{\pi}\\\\we\ accept\ the\ approximation\ of\ \pi\approx3.14\\\\r=\frac{8}{\pi}\approx\frac{8}{3.14}\approx2.5\ (ft)$

(x + 130, y - 55)

Step-by-step explanation: If the southeast corner of the pole barn is the only reference point, it only requires this one point and not the size of the barn.

Let's set this up first: West/South= Negative x/y, and East/North= Positive x/y.

Currently, the corner is at -50, 25. The corner needs to be moved to 80, -80.

For x: |-50|+80=130

For y: |25|+(-80)=-55

The formula for this is |a|+b=c.

This leaves it with (x + 130, y - 55)
