Question

If there is a sphere with a volume of 1761.1 meters cubed, what is the radius?

Answer 1

$\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}\quad \begin{cases} r=radius\\ -----\\ V=1761.1 \end{cases}\implies 1761.1=\cfrac{4\pi r^3}{3} \\\\\\ 3(1761.1)=4\pi r^3\implies \cfrac{3(1761.1)}{4\pi }=r^3\implies \sqrt[3]{\cfrac{3(1761.1)}{4\pi }}=r$
