What is the best approximation for the area of a circle with a radius of 4 m ? use 3.14 to approximate pi
Answers: 1
![\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=4 \end{cases}\implies A=\pi 4^2\implies A=16\pi \implies \stackrel{\pi =3.14}{A=50.24}](/tpl/images/0001/5375/3ec19.png)
