Answer:
Volume=2521.91 mm³
Step-by-step explanation:
d=13, r=13/2=6.5, h=19
volume=πr²h
=π(6.5)²×19
=<u>2521.91 mm³</u>

The number of solutions of a quadratic equation
ax^2+bx+c=0
Depends on its discriminant
/Delta=b^2-4ac
If /Delta>0 there are two distinct solutions
If /Delta=0 there are two coincident solutions
If /Delta<0 there are no solutions.
We know that there are two real solutions (I assume you mean distinct solutions), so we know that the discriminant is positive:

b^2-4ac=9+28t>0\iff t>-\dfrac[9][28]
You seem to already see that you need to multiple x with the other numbers. When you start off solving it you'd get.. x-6=x2(to the power of) + 6x . Then just move the equation over from the left to the right. and solve, I've got -6+x2(power of 2)+7x, that's it
