Penjelasan dengan langkah-langkah:
volume bola =
[tex]v = \frac{1}{2} \times \frac{4}{3} \times \frac{22}{7} \times {r}^{3} \\ 2425.5 \: = \frac{44}{21} \times {r}^{3} \\ 2425.5 \times 21 = 44 \times {r}^{3} \\ 50935.5 = 44 \times {r }^{3} \\ \frac{50935.5}{44} = {r}^{3} \\ 1157.625 = {r}^{3} \\ \sqrt[3]{1157.625} = r \\ 10.5 \: cm = r[/tex]
[tex]d = 2r \\ = 2(10.5 \: cm) \\ = 21 \: cm[/tex]
