Respuesta:
R// [tex]-\frac{a^{2} }{2b} +\frac{b}{2} +\frac{c^{2} }{2b} =X[/tex]
R// [tex]r=\sqrt{\frac{\pi }{A} }[/tex]
Explicación paso a paso:
[tex]a^{2} =b^{2} +c^{2} -2bx[/tex] despejar x
[tex]a^{2} -b^{2} -c^{2} =-2bx[/tex]
[tex]\frac{a^{2} - b^{2} - c^{2} }{-2b} =X[/tex]
[tex]-\frac{a^{2} }{2b} +\frac{b}{2} +\frac{c^{2} }{2b} =X[/tex]
----------------------------------------------------------
[tex]A=\pi *r^{2}[/tex]
[tex]\frac{A}{\pi } =r^{2}[/tex] para eliminar el exponente se saca raíz cuadrada a los dos lados
[tex]r=\sqrt{\frac{\pi }{A} }[/tex]
