tolong Bantu karena besok buat pr plizz

[tex]1. \\ volume = 3.14 \times 10 \times 10 \times 20 = 6280{cm}^{3}[/tex]
[tex]2. \\ volume = \frac{22}{7} \times 3.5 \times 3.5 \times 20 = 770{cm}^{3}[/tex]
[tex]3. \\ masih \: kurang \: yakin \: (maaf \: salah) \\ volume \frac{12 \times 18}{2} \times 28 = 3024 {cm}^{3} [/tex]

[tex]4. \\ 512 = {r}^{3} \\ r = \sqrt[3]{512} \\ r = 8 \: cm[/tex]
[tex]5. \\ volume = \frac{1}{3} \times luas \: alas \times tinggi \\ volume = \frac{1}{3} \times 144 \times 8 = 384 {dm}^{3} [/tex]
[tex]6. \\ 450 = luas \: alas \times 15 \\ luas \: alas = 30 {cm}^{2} [/tex]
[tex]7. \\ 588 = luas \: alas \times 7 \\ luas \: alas = 84 {cm}^{2} [/tex]
[tex]8. \\ volume = \frac{1}{3} \times \frac{22}{7} \times 14 \times 14 = 5544 {cm}^{3} [/tex]
[tex]9. \\ volume = \frac{22}{7} \times 21 \times 21 \times 8 = 11088 {cm}^{3} [/tex]
[tex]10. \\ volume = 24 \times 15 \times 5 = 1800 {cm}^{3} [/tex]

Maaf kalo salah, semoga membantu
