The amount out of the 5 people doing something most likely :)
Answer: -4x+c
Step-by-step explanation:
It’s already simplified
Check the picture below.
now, let's rationalize the denominator for "r" first.
also notice, that section is just 1/4 of the area of that circle, so, let's just find the area of the whole circle with that "r", get one-quarter of it, and subtract it from the half of the area of the square.
![\bf r=\cfrac{8}{\sqrt{2}}\cdot \cfrac{\sqrt{2}}{\sqrt{2}}\implies r=\cfrac{8\sqrt{2}}{2}\implies \boxed{r=4\sqrt{2}} \\\\\\ \stackrel{\textit{area of that circle}}{A=\pi (4\sqrt{2})^2}\implies A=\pi (16\cdot 2)\implies A=32\pi \\\\\\ \textit{how much is one-quarter of that?}\quad \cfrac{32\pi }{4}\implies \boxed{8\pi }\\\\ -------------------------------\\\\](https://tex.z-dn.net/?f=%5Cbf%20r%3D%5Ccfrac%7B8%7D%7B%5Csqrt%7B2%7D%7D%5Ccdot%20%5Ccfrac%7B%5Csqrt%7B2%7D%7D%7B%5Csqrt%7B2%7D%7D%5Cimplies%20r%3D%5Ccfrac%7B8%5Csqrt%7B2%7D%7D%7B2%7D%5Cimplies%20%5Cboxed%7Br%3D4%5Csqrt%7B2%7D%7D%0A%5C%5C%5C%5C%5C%5C%0A%5Cstackrel%7B%5Ctextit%7Barea%20of%20that%20circle%7D%7D%7BA%3D%5Cpi%20%284%5Csqrt%7B2%7D%29%5E2%7D%5Cimplies%20A%3D%5Cpi%20%2816%5Ccdot%202%29%5Cimplies%20A%3D32%5Cpi%20%0A%5C%5C%5C%5C%5C%5C%0A%5Ctextit%7Bhow%20much%20is%20one-quarter%20of%20that%3F%7D%5Cquad%20%5Ccfrac%7B32%5Cpi%20%7D%7B4%7D%5Cimplies%20%5Cboxed%7B8%5Cpi%20%7D%5C%5C%5C%5C%0A-------------------------------%5C%5C%5C%5C)
