So I was doing my basic pre-cal level homework and I bumped into this question. Easy right? P = 20 [ft] C of Cir = 2(pi)(r), areas of cir is = pi(r^2) where r is radius I know this is easy... yet I can not wrap my head around the question? Maybe it is just my brain being weird and I will get it tomorrow morning. The problem is I am not sure what to solve for or what to do!
