Answer:
5.
[tex][tex]volume = \pi \: {r}^{2} \times h \\ = \pi \times 3. {5}^{2} \times 7 \\ = \pi \times 12.25 \times 7 \\ = 38.48 \times 7 \\ = 269.39 \\ [/tex]
6
[tex][tex]volume = \frac{4\pi \times {8}^{3} }{3 } \\ = \frac{4\pi \times 512}{3} \\ = \frac{6.433.98}{3} \\ = 2.144.66[/tex]
7.
[tex][tex]volume = {a}^{2} \times \frac{h}{3} \\ = {10}^{2} \times \frac{13}{3} \\ = 100 \times 4.33 \\ = 433.33 [/tex]
8.
[tex]volume = \pi {r}^{2} \times h \\ = \pi \times 3. {1}^{2} \times 17.9 \\ = \pi \times 9.16 \times 17.9 \\ = 30.19 \times 17.9 \\ = 540.41[/tex]
9.
[tex]volume = \frac{\pi {r}^{2} \times h }{3} \\ = \frac{\pi \times 32 \times 4}{ 3} \\ = \frac{\pi \times 9 \times 4}{3} \\ = \frac{113.1}{3} \\ = 37.7[/tex]
