I think the answer would have to be D. If the diameter, which is the distance from one point on the circle through the center to another point on the circle, is halved then the amount of concrete that will be needed will be multiplied by 4. I think that's right I am so sorry in advance if that was incorrect. Have a beautiful rest of your day. Stay safe. C O V I D - 1 9 IS REAL THIS COULD MEAN YOUR LIFE!!!
I don't totally understand,but maybe it's 6(-31)=-186.
I don't really understand the question?

Answer:

Step-by-step explanation:
Given:

Now, from the figure shown below,
The sum of angle efh and angle hfg is equal to the angle efg. This is true because of the angle addition postulate which states that when two angles are formed with the same vertex and different sides, then their sum is equal to the total angle made by both the sides at the vertex.
Here, point 'f' is the vertex and the sides are 'ef and 'fg'.
Therefore,

Plug in their values and solve for 'x'. This gives,

Therefore, the angle measure of each are:

Since the prism completely filled with 2304 cubs
Since the edge of the cube is 1/4 cm
Since the volume of the cube = edge x edge x edge
Then find the volume of 1 cube, then multiply it by the number of cubes to find the volume of the prism

Multiply it by 2304

The volume of the prism is 36 cm^3
