$R = ^3\sqrt{\frac{3}{4} * \frac{V}{π}} = ^3\sqrt{\frac{3}{4} * \frac{4\frac{4}{21}}{π}} = ^3\sqrt{\frac{3}{4} * \frac{\frac{88}{21}}{π}} = ^3\sqrt{\frac{3 * 88 * 7}{4 * 21 * 22}} = ^3\sqrt{\frac{1}{1}} = 1$ (м)

$R = ^3\sqrt{\frac{3}{4} * \frac{V}{π}} = ^3\sqrt{\frac{3}{4} * \frac{33\frac{11}{21}}{π}} = ^3\sqrt{\frac{3}{4} * \frac{\frac{704}{21}}{π}} = ^3\sqrt{\frac{3 * 704 * 7}{4 * 21 * 22}} = ^3\sqrt{\frac{704}{88}} = ^3\sqrt{8} = 2$ (м)

$R = ^3\sqrt{\frac{3}{4} * \frac{V}{π}} = ^3\sqrt{\frac{3}{4} * \frac{\frac{99}{448}}{π}} = ^3\sqrt{\frac{3 * 99 * 7}{4 * 448 * 22}} = ^3\sqrt{\frac{3 * 9}{4 * 64 * 2}} = ^3\sqrt{\frac{3^3}{8^3}} = \frac{3}{8}$ (м)

$R = ^3\sqrt{\frac{3}{4} * \frac{V}{π}} = ^3\sqrt{\frac{3}{4} * \frac{\frac{392}{363}}{π}} = ^3\sqrt{\frac{3 * 392 * 7}{4 * 363 * 22}} = ^3\sqrt{\frac{49 * 7}{121 * 11}} = ^3\sqrt{\frac{7^3}{11^3}} = \frac{7}{11}$ (м)
