Question

comparati 36π cu 216-36π. (3,14<π<3,15)​

Answer 1

$3.14<\pi<3.15\Big|\cdot 36 \Rightarrow 113.04<36\pi <113.4\quad (1)\\ \\ 3.14<\pi<3.15\Big|\cdot (-36) \Rightarrow -113.4<-36\pi<-113.04 \Big|+216 \Rightarrow \\ \\ \Rightarrow 102.6 <216-36\pi < 102.96\quad (2) \\ \\\\\text{Din (1) si (2):}\\\\216-36\pi < 102.96\\\\ 36\pi >113.04>102.96>216-36\pi\\ \\ \Rightarrow \boxed{36\pi >216-36\pi}$
