Answer:
The expression that gives the volume of the cylinder in cubic inches is
.
Step-by-step explanation:
The base of a cylinder is a circle, the area of that circle is given by the formula:
area = 
Multiplying by the height
we get that the volume of a cylinder is

where:
π = Pi
<em>r</em> = the radius of the circular end of the cylinder
<em>h = </em>height of the cylinder
We know that the cylinder has a height of <em>h</em> inches and a diameter of 3 inches.
The radius of a circle is half the diameter and the volume is:

Answer:
z = y
Step-by-step explanation:
x+y=z
y−z=x
Substitute the second equation in for x
y -z +y = z
Add z to each side
2y -z+z = z+z
2y = 2z
y =z
First find volume of prism by doing l*w*h so 12*4*6=288
Then find volume of triangular prism by doing 1/2*b*h*l so 1/2*6*6*4=72
Lastly add these 2 together for the volume of the entire composite shape:
288+72
=360
