Can someone please tell me what I'm doing wrong? I think I know how to do quadratic formula, and I know all the steps, but the l

Nata [24]

Okay, so first you set equal to 0:
$6-6x^{2}=3x\\-6x^{2}-3x+6=0$

Next simplify the equation so that the leading coefficient is positive:
$\frac{-6x^{2}-3x+6}{-3}=\frac{0}{3}\\2x^{2}+x-2=0$

Looking at the quadratic equation you can't easily simplify it, so plug it into the quadratic equation and simplify:
$x=\frac{-b\ -+\ \sqrt{b^{2}-4ac}}{2a}\\\\x=\frac{-(1)\ -+\ \sqrt{(1)^{2}-4(2)(-2)}}{2(2)}\\\\x=\frac{-1\ -+\ \sqrt{1+16}}{4}\\\\x=\frac{-1\ -+\ \sqrt{17}}{4}*\frac{-1}{-1}\\\\x=\frac{1\ -+\ \sqrt{17}}{-4},\ or\ B.$

I noticed a couple mistakes in your work, so if you want me to I can explain them in the comments section :)

Answer:

485.9 mm³

Step-by-step explanation:

The volume of a sphere is 4/3 π r³. So the volume of a hemisphere is half of that:

V = 128π/3

The formula for the volume of a cylinder is V = Bh or V = πr²h .

The radius of the cylinder is 4mm and the height is 7mm

Substitute 4 for r and 7 for h in the formula V = πr²h .

V = 112π

Since the figure is made up of a hemisphere and cylinder so volume will be sum of these two shapes

= 485.9 mm³
