mohon bantuannya!!! ps:dgn caranya

[tex]6. \\ \frac{150}{360} \times 24 \times 24 \times \pi = r \times 24 \times \pi \\ 240 = 24r \\ r = 10 \: cm[/tex]
[tex]7. \\ luas \: 1 = luas \: 2 \\ rumus \: luas \: = 4 \times \pi \times r \times r\\ 4 \times \pi \times 3 \times 3 = 4 \times \pi \times 4 \times 4 \\ 9 = 16[/tex]
[tex]8. \\ volume \: bola = 113.4l = 113400 {cm}^{3} \\ rumus \: volume = \frac{4}{3} \times \pi \times r \times r \times r \\ 113400 = \frac{4}{3} \times 3.14 \times {r}^{3} \\ 27085.98 = {r}^{3} \\ r = 30.04[/tex]
[tex]9. \\ volume \: \frac{1}{2} \: bola = \frac{1}{2} \times \frac{4}{3} \times \frac{22}{7} \times 14 \times 14 \times 14 \\ volume \: \frac{1}{2} \: bola = 5749.33 {cm}^{3} = 5.74933 \: liter[/tex]
10. saya tidak tau, maaf ^_^

Maaf kalo salah, semoga membantu
