The answer is 8/3 I think
1540.5 .
V=PI*R^2*H/3=3.14*9.5^2*5.433=1540;5
The equation has 0 real solutions.
If an equation has a negative discriminant, than there are no real solutions. We know this because the quadratic formula requires you to take the square root of the discriminant and therefore you would have all imaginary numbers.
