Answer:
h = 6 cm
Step-by-step explanation:
Volume of cylinder = 54 π cm³
πr²h = 54π
π * 3 * 3 * h = 54π
Answer:
No solution.
Step-by-step explanation:
So we have the system of equations:
We can solve this by substitution. Substitute the first equation into the second. Thus:
Distribute the right:
Subtract 4y from both sides:
Subtract the right:
As you can see, this statement is not true. In other words, the system of equations have no solution (likely because the lines are parallel).
And we're done!
