A hemisphere with a 90 degree slice removed and a radius of 8 what is the volume

Okay...so since 90 degrees out of 360 is taken out that means that the hemisphere is only 250 degrees. That's only 3/4 of a hemisphere. So, you need to find the volume of the hemisphere as if it were a sphere. Then, you divide that by 2 to get the volume of the hemisphere. Then, you multiply it by 3/4 to get the volume of your sliced hemisphere.

Answer:

7.1

Step-by-step explanation:

write pythagorean theorem $x^{2}$ + $x^{2}$ = $10^2$

2 $x^2$ = 100

divide 2 both side:

$x^{2}$ = 50

$\sqrt{x^2}$ = $\sqrt{50}$

$x$ = $\sqrt{50}$

$x$ = 7.07106781

round to nearest tenth:

$x$ = 7.1

The work of a student to solve the equation 3(3y − 8) = 10 + 3y is shown below:

Step 2 9y - 24 = 10 + 3y because 3 times 3y its not 6y nor is 3 times 8 equal to 5

Simply (2)/(3)a+6-(3)/(5)a-1

Bas_tet [7]

Answer:

That simplifies to $\frac{1}{15}a + 5$

Step-by-step explanation:

Let's simplify:

$\frac{2}{3}a + 6 - \frac{3}{5}a - 1\\\\\frac{10}{15}a - \frac{9}{15}a + 6 - 1\\\\\frac{1}{15}a + 5$

If you want to express that as a single fraction, you can do so by multiplying the five by 15/15, and summing the numerators. That gives you:

$\frac{a + 75}{15}$
