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...

Angle one and angle two are a linear pair . M angle one = 3x-30 , and angle two = x+76 . Find the measure of each angle .

ad-work [718]

linear pairs are supplementary so their sum equals 180°

(3x - 30) + (x + 76) = 180

4x + 46 = 180

4x = 134

x = 33.5

∠1: 3x - 30 = 3(33.5) - 30 = 70.5

∠2: x + 76 = (33.5) + 76 = 109.5

Answer: ∠1 = 70.5°, ∠2 = 109.5°
