The solid shape is a cone and a half sphere. So the equation would be (cone volume) + (1/2 sphere volume):
$cone = \frac{1}{3} \pi {r}^{2} h \\ sphere = \frac{4}{3} \pi {r}^{3} \\ object = ( \frac{1}{3} \pi {r}^{2} h) + \frac{1}{2} ( \frac{4}{3} \pi {r}^{3} )$
If the volume of the cone is 270pi and the height of the cone is 10, then:
$270\pi = \frac{1}{3} \pi {r}^{2} (10) \\ 27 = \frac{1}{3} {r}^{2} \\ 80 = {r}^{2} \\ r = 9$
The radius of the object is 9 cm. Therefore, we can plug into the formula for the total volume:
$object = 270\pi + \frac{1}{2} ( \frac{4}{3} \pi {(9)}^{3} ) \\ = 270\pi + \frac{2}{3} (729\pi) \\ = 270\pi \: + 243\pi \\ = 513\pi$
The total volume is 513 pi cm^3

Find the missing variables pythagorean theorem

worty [1.4K]

Answer:

y = 12 x = 12√2 z = 12√3

Step-by-step explanation:

The 45° triangle will also have a height of y so....

y² + y² = x² 2y² = x² y² = x²/2 y = √(x²/2)

The 30° triangle

y² + z² = 24² y² = 24² - z² y = √(24² - z²)

sin 30 = y/24 1/2 = y/24 y = 12

y² = x²/2

12² = x²/2²

2(144) = x² x = √(288) x = 12√2

y² + z² = 24²

z² = 24² - y²

z² = 24² - 12²

z² = 576 - 144

z² = 432

= √(16·9·3)

z = 4·3√3

z = 12√3

y² + z² = 24²

12² + (12√3)² = 24²

144 + 144·3 = 576

2y² = x²

2(12)² = x²

288 = (12√2) = 144·2 = 288
