A machine part consists of a half-sphere and a cylinder, as shown in the figure.
The total volume of the part is _ π cubic inches.

  126π in³

Step-by-step explanation:

The volume of the figure is the sum of the volumes of the cylinder and hemisphere. The radius is half the diameter, so is 3 in. The volume formula for this figure is ...

  V = πr²h +2/3πr³ = πr²(h +2/3r)

  V = π(3 in)²(12 in + 2/3(3 in)) = π(9 in²)(14 in)

  V = 126π in³

The volume of the part is 126π cubic inches.

i dont understand the question? ?

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
