Find the common ratio of the sequence. –172, –86, –43, –21.5, . . .

seropon [69]

If you divide each number by the previous one, you get:

-86 / -172 = 1/2
-43 / -86 = 1/2
-21.5 / -43 = 1/2

The common ratio is 1/2 = 0.5

The diagram shows a solid shape.

Stolb23 [73]

Answer:

$756\pi$

Solution,

Volume of cone=270 pi cm^3

$\frac{1}{3} \pi \: {r}^{2} = 270\pi \\ or \: {r}^{2} \times 10 = 270 \times 3 \\ or \: {r}^{2} \times 10 = 810 \\ or \: {r}^{2} = \frac{810}{10} \\ or \: {r}^{2} = 81 \\ or \: r = \sqrt{81} \\ or \: r = \sqrt{ {9}^{2} } \\ r = 9 \: cm$

Volume of semisphere:

$\frac{2}{3} \pi {r}^{3} \\ = \: \frac{2}{3} \times \pi \times 9 \times 9 \times 9 \\ = 486\pi$

Total:

$270\pi + 486\pi \\ = 756\pi$

hope this helps...

Good luck on your assignment..
