Question

${7}^{2} = \frac{4 {\pi}^{2} }{g \times m} \times {r}^{2}$
ayudenme a despegar la r​

Answer 1

$\textbf{Despejamos:}\\\\7^2=\dfrac{4\pi^2}{g\times m}\times r^2\\\\\\7^2=\dfrac{4\pi^2r^2}{gm}\\\\\\7^2gm=4\pi^2r^2\\\\\\\dfrac{7^2gm}{4\pi^2}=r^2\\\\\\\sqrt{\dfrac{7^2gm}{4\pi^2}}=r\\\\\\\boxed{\dfrac{7\sqrt{gm}}{2\pi}=r}$

$\textbf{Respuesta:}\\\\ r=\dfrac{7\sqrt{gm}}{2\pi}$
