Answer 1

Penjelasan dengan langkah-langkah:

[tex]1) \: {l}^{selimut \: tabung} =2 \times \pi \times r \times t \\ {l}^{tabung} = 2 \times \pi \times r \times (r + t) \\ {v}^{tabung} = \pi \times {r}^{2} \times t[/tex]

[tex]2) \: {l}^{selimut \: tabung} = 2 \times \pi \times r \times t \\ \\ = 2 \times \frac{22}{7} \times 7 \times 9 \\ \\ = 2 \times \frac{22}{7} \times 63 \\ \\ = 2 \times 198 \\ = 396 \: {cm}^{2} [/tex]

[tex]3) \: {l}^{tabung} = 2 \times \pi \times r \times (r + t) \\ \\ = 2 \times 3.14 \times 6 \times (6 + 10) \\ \\ = 2 \times 3.14 \times 6 \times 16 \\ \\ = 2 \times 3.14 \times 96 \\ \\ = 2 \times 301.44 \\ = 602.88 \: {cm}^{2} \\ [/tex]

[tex]4) \: {v}^{tabung} = \pi \times {r}^{2} \times t \\ \\ = \frac{22}{7} \times {14}^{2} \times 11 \\ \\ = \frac{22}{7} \times 196 \times 11 \\ \\ = \frac{22}{7} \times 2.156 \\ \\ = 6.776 \: {cm}^{3} [/tex]

[tex]5) \: {l}^{tabung} = \pi \times r \times (r + 2 \times t) \\ \\ = \frac{22}{7} \times 7 \times (7 + 2 \times 14) \\ \\ = \frac{22}{7} \times 7 \times 9 \times 14 \\ \\ = \frac{22}{7} \times 7 \times 126 \\ \\ = \frac{22}{7} \times 882 \\ \\ = 2.772 \: {cm}^{2} [/tex]

[tex]6) \: t = \frac{volume}{\pi \times {r}^{2} } \\ \\ = \frac{1.540}{ \frac{22}{7} \times {7}^{2} } \\ \\ = \frac{1.540}{ \frac{22}{7} \times 49 } \\ \\ = \frac{1.540}{154} \\ \\ = 10 \: cm[/tex]

[tex]7) \: {l}^{selimut \: tabung} = 2 \times \pi \times r \times t \\ \\ = 2 \times \frac{22}{7} \times 14 \times 15 \\ \\ = 2 \times \frac{22}{7} \times 210 \\ \\ = 2 \times 660 \\ \\ = 1.320 \: {cm}^{2} [/tex]

[tex] {l}^{tabung} = 2 \times \pi \times r \times (r + t) \\ \\ = 2 \times \frac{22}{7} \times 14 \times (14 + 15) \\ \\ = 2 \times \frac{22}{7} \times 14 \times 29 \\ \\ = 2 \times \frac{22}{7} \times 406 \\ \\ = 2 \times 1.276 \\ \\ = 2.552 \: {cm}^{2} [/tex]

[tex] {v}^{tabung} = \pi \times{r}^{2} \times t \\ \\ = \frac{22}{7} \times {14}^{2} \times 15 \\ \\ = \frac{22}{7} \times 196 \times 15 \\ \\ = \frac{22}{7 } \times 2.940 \\ \\ = 9.240 \: {cm}^{3} [/tex]
