Solve the formula V=pir^2h for r <br><br> PLEAASSSEEE HELP

otez555 [7]

Answer:

Step-by-step explanation:

So we have the formula:

$V=\pi r^2h$

And we want to solve it for r.

So, let's first divide both sides by π and h. This will cancel out the right side:

$r^2=\frac{V}{\pi h}$

Now, take the square root of both sides:

$r=\sqrt{\frac{V}{\pi h}}$

And we're done!

Our answer is B.

I hope this helps!

Finding domain f(x)=3x+1/x-5

arlik [135]

The function is undefinded if the denominator, x-5, equals 0.
So $x-5 \neq 0 \\ 
x \neq 5$ .
The domain is $x \neq 5$ .
In interval notation, this is (-infinity, 5) u (5, infinity).
