Answer: 83.78 cm^3

pi times the radius squared times the height divided by 3, when you know the diameter, you simply divide by two to find the radius, which you then plug into the formula.

Explanation:

First you had to square from both sides of equation form.

$(\sqrt{x-6+2})^2=6^2$

Then you expanded form.

$(\sqrt{x-6+2})^2=x-4$

$x-4=36$

$6^2=6*6=36$

Solve by equation form.

$x-4=36$

Add by four from both sides of equation form.

$x-4+4=36+4$

Simplify.

$x=40$

Verified solutions.

$x=40 \boxed{TRUE}$

Final answer: $\boxed{x=40}$

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

Factor −1/2−1/2 out of −1/2x+6.

pochemuha

That's unusual: repetition: -1/2 - 1/2.

Did you perhaps mean "Factor -1/2 out of (-1/2)x + 6?

Let's do that. Let's rewrite 6 as (-1/2)(-12).

Then (-1/2)x + 6 (-1/2)x -(1/2)(-12)
-------------- = ------------------------ = x - 1/2
-1/2 -1/2

Hope that's what you wanted. If not, please try to apply a similar approach to solving this particular problem.
