Question

Juanita and Lauren are painting a mural. The area of the mural is 33 square meters. What is the radius?

Answer 1

`\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ A=33 \end{cases}\implies 33=\pi r^2\implies \cfrac{33}{\pi }=r^2 \\\\\\ \sqrt{\cfrac{33}{\pi }}=r\implies 3.241022407214287\approx r`
