$$\frac{\mathrm{3}−{a}}{{r}}\:=\:\frac{{h}}{{R}} \\ $$$$\frac{\mathrm{3}−{a}}{\left(\frac{{a}}{\:\sqrt{\mathrm{2}}}\right)}\:=\:\frac{\mathrm{3}}{\mathrm{1}} \\ $$$$\mathrm{3}\sqrt{\mathrm{2}}\:−\sqrt{\mathrm{2}}{a}\:=\:\mathrm{3}{a} \\ $$$${a}\:=\:\frac{\mathrm{3}\left(\mathrm{3}\sqrt{\mathrm{2}}\:−\mathrm{2}\right)}{\mathrm{7}} \\ $$
