<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.

Answer:

The step 4 is not what he should have done. But the wrong is step 5, because if he added -2x both sides, it would give the following equation:

$x-12=-4x+6$

and not $x-12=6$

Note that in step 4 he should have added 2x and not -2x to both sides, but we still have the equality. The problem is that step 5 is totally wrong.

I don't know what answer is expected to this question, but I would mark step 5, because this is mathematically wrong.

Solving the equation

$3(x-4)=-4-2(x-5)$

Using distribution

$3x-12=-4-2x+10\\3x-12=-2+6$

Add $2x$ both sides

$3x-12+2x=-2x+6+2x$

$5x-12=6$

Add 12 both sides

$5x-12+12=6+12\\5x=18$

Divide both sides by 5

$x=\frac{18}{5}$

What is the diameter of a circular swimming pool with a radius of 8 feet?

Alenkasestr [34]

We know that,

diameter is twice the radius, I.e d = 2r

Now d = 2(8)ft = 16 feet
