"As shown" ?  You have a picture to work with but you're not sharing it ? 
Fortunately, the question includes all the information that's needed to answer it,
so I don't need to see the picture.
The volume of a cylinder is (pi) x (radius)² x (height) .
Radius = 1/2 of the diameter = 15 mm
Volume = (pi) x (15 mm)² x (30 mm) = 6,750 pi mm³ = 21,205.75 mm³ .
That's a correct answer, but the number is slightly awkward and inconvenient.  Let's
change it to a bigger unit, so the number will be smaller and easier to carry around.
Remember that 10 mm = 1 cm
So (10 mm)³ = 1,000 mm³ = 1 cm³
and 21,205.75 mm³ = 21.20575 cm³
        
             
        
        
        
Answer:
   x = {-4, 4}
Step-by-step explanation:
Subtracting 3 gives ...
   5x^2 = 80
Dividing by 5, we get ...
   x^2 = 16
Taking the square root gives the solutions ...
   x = ±4
The smaller value of x is -4; the larger value is 4.

Answer:
1,000,000
Step-by-step explanation:
1mm=1e-6km
10mm=1e-5km
100mm=1e-4km
1000mm=000.1km
10000mm=0.01km
100000mm=0.1km
500000mm=0.5km
1000000mm=1km
 
        
             
        
        
        
The slope is 2.
The slope is 1/2.
The y intercept is 4.
The y intercept is 8
The points (-2,-5) and (8,0) are also on the line
The points (-5,-2) and (1,10) are also in the line.
