Incorrect. We are given $\displaystyle{1.5}=\pi\sqrt{{\frac{{L}}{{245}}}}\usepackage{cmbright}\Huge\$ and want to solve for L. Divide both sides of the equation by $\displaystyle\pi\usepackage{cmbright}\Huge\$ , then square both sides of the equation to get rid of the radical and continue to solve for L.
