Answer: Option B
Step-by-step explanation:
The formula for calculate the volume of a hemisphere is:

Where r is the radius:
The formula for calculate the volume of a cylinder is:

Where r is the radius and h is the height.
Therefore, the volume of the figure is the sum of the volume of the hemisphere and the volume of the cylinder.
Finally, knowing that the radius of the hemisphere and the cylinder is 6 inches and the height of the cylinder is 12 inches, you can substitute values. Then:

Answer:
87.5(the first one)
Step-by-step explanation:
first simplify 4 to the 5th power(20) and multiply by 4 to the -7th(-35) and you will get -700 divide that by 4 to the -2nd(-8) and you will get 87.5
The formula would be 1 side to the power of the the ((answer=2)) because {2x2x2=8}
Answer:
12x - 6
Step-by-step explanation:
8x - 3 + 4x - 3
12x - 6
x = - 2
