Answer:

V(hemisphere) = 1072.3in^3

Step-by-step explanation:

To find the volume of a hemisphere, we will have to take the volume of a sphere as a whole and divide it by 2. This is because a hemisphere is half of a sphere.

The volume of a sphere is:

Let's plug in the radium of 8 into the equation and solve:

Now, divide it by 2

V(sphere) = (2144.660585)/2

V(hemisphere) = 1072.3in^3

I hope this helps!!

Answer:

x = 5

Explanation:

Well, there's a theorem about these triangles that helps you solve questions similar to this one.

The theorem states that the sum of the two angles of a triangle is equal to the magnitude of the angle exterior to them.

That is, 33° + (10x+1)° = (17x-1)°

17x - 10x = 33 + 1 + 1

7x = 35 => x = 5

Hope it helps you, mate! :)
