Determine the volume
The volume of a cylinder is calculated as thus:

Substitute values for r and h


<em>Hence, the volume of the cylinder is 18312.48mm³</em>
Answer:
16 cups
Step-by-step explanation:
5x8=40
2x8=16
Subtract the second equation from double the first equation:
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0. Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).
2.500.000 is the answer but I think simplifying it would make it 2.5?
