Question

Can someone help me find the area of this circle and round to the nearest tenth

Answer 1

the circle has a diameter of 12, thus its radius is half that, or 6.

`\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=6 \end{cases}\implies A=\pi 6^2\implies A=36\pi \\\\\\ A \approx 113.0973355\implies A=\stackrel{\textit{rounded up}}{113.1}`
