tolong bantu jawab ya, soalnya besok harus dikumpulkan, Terima kasih;)​

Answer 1

Volume tabung = π x r²x t

[tex]2.310 = \frac{22}{7} \times {r}^{2} \times 15 \\ \\ 2.310 = \frac{330}{7} \times {r}^{2} \\ \\ 2.310 \times \frac{7}{330} = {r}^{2} \\ \\ {r}^{2} = 49 \\ \\ r = \sqrt{49} \\ \\ r = 7 \: cm[/tex]
