Answer:

All Real Numbers Are Solutions

Explanation:

9x + 27 = 9(x + 2) + 9

Simplify both sides of the equation.

9x + 27 = 9(x + 2) + 9

9x + 27 = (9)(x) + (9)(2) + 9 (Distribute)

9x + 27 = 9x + 18 + 9

9x + 27 = (9x) + (18) (Combine Like Terms)

9x + 27 = 9x + 27

Subtract 9x from both sides.

9x + 27 − 9x = 9x + 27 − 9x

27 = 27

Subtract 27 from both sides.

27 − 27 = 27 − 27

0 = 0

Therefore, all real numbers are solutions.

<h3>Given:</h3>

h= 19 ft
r= 12 ft

h= Height
r= Radius

The volume of the given cone.

<h3>Solution:</h3>

$\large\boxed{Formula:V= \frac{1}{3}\pi{r}^{2}h}$

$\large\boxed{\red \pi \red = \red 3 \red . \red 1 \red 4}$

Let's solve!

Substitute the values according to the formula.

$V=\frac{1}{3}×3.14×{12}^{2}×19$

$\large\boxed{V=2863.68 \: {ft}^{3}}$

Therefore, the volume of the given cone is 2863.68 cubic feets.
