Answer:
opt 4
Step-by-step explanation:
when x=0, 0+3y= -3, so y=-1 (0,-1) is solution
when x=3 , 21+3y=-3, 3y= -3-21= -24
y= -8 (3,-8) is also solution

Explanation:</h2>
A composite figure is formed by two or more basic figures or shapes. In this problem, we have a composite figure formed by a cylinder and a hemisphere as shown in the figure below, so the volume of this shape as a whole is the sum of the volume of the cylinder and the hemisphere:

So:

From the figure the radius of the hemisphere is the same radius of the cylinder and equals:

And the height of the cylinder is:

So:

The volume of a hemisphere is half the volume of a sphere, hence:

Finally, the volume of the composite figure is:
