Givens
V = 209.3 in^3
pi = 3.14
h = 8 in

Formula
V = 1/3 pi r^2 h
209.3 = 1/3 * 3.14 * r^2 * h Multiply both sides by 3
209.3 * 3 = 3.14 * r^2 * 8
627.9 = 3.14 * r^2 Divide by 3.14
627.9/3.14 = r^2 * hThis rounds to 200
199.968 = r^2 * 8
8*r^2 = 199.968 Divide by 8
r^2 = 199.968 / 8
r^2 = 24.996
r = sqrt(24.996)
r = 4.9996 That's not quiet the answer.

diameter = 2*r
diameter = 2* 4.9996
diameter = 9.9992
d = 9.9992 <<<<< answer

You might want to think about rounding to 10 when you enter your answer.

Answer:

$f(x)=\dfrac{x+2}{2(x-2)}$

Step-by-step explanation:

Remember when you divide fractions, you need to get the reciprocal of the divisor and multiply. So your first simplification would be:

$\dfrac{x^2+4x+4}{x^2-6x+8}\div\dfrac{6x+12}{3x-12}\\\\=\dfrac{x^2+4x+4}{x^2-6x+8}\times\dfrac{3x-12}{6x+12}\\\\=\dfrac{(x^2+4x+4)(3x-12)}{(x^2-6x+8)(6x+12)}$

Next we factor what we can so we can further simplify the rest of the equation:

$=\dfrac{(x^2+4x+4)(3x-12)}{(x^2-6x+8)(6x+12)}\\\\=\dfrac{(x+2)(x+2)(3x-12)}{(x^2-6x+8)(6(x+2))}\\\\$

We can now cancel out (x+2)

$=\dfrac{(x+2)(3x-12)}{(x^2-6x+8)(6)}$

Next we factor out even more:

$=\dfrac{(x+2)(3)(x-4)}{(x-2)(x-4)(6)}$

We cancel out x-4 and reduce the 3 and 6 into simpler terms:

$=\dfrac{(x+2)(1)}{(x-2)(2)}$

And we can now simplify it to:

$=\dfrac{x+2}{2(x-2)}$
