Here's the formula for the volume of a cone:

V=\frac{1}{3}\pi\ r^2h

Plug in 3.14 for \pi.
Plug in 6 for the height h.
Our radius is half of our diameter. r=6.

V\approx\frac13\times3.14\times6^2\times6

6² = 6 × 6 = 36.
Now we just multiply together 1/3, 3.14, 36, and 6 to get...

V\approx226.08

Rounding to the nearest tenth...

\boxed{V\approx226.1\ ft^3}

Cone formula: 1/3(\pi r^{2} h)
     
Step 1(Fill in formula): 1/3((3.14)(6^{2})(6))
Step 2 (Solve): 1/3((3.14)(36)(6))
Step 3 (Solve): 1/3(678.24)
Step 4 (Complete) : 226.08ft³

Find 2x2 − 2z4 + y2 − x2 + z4 if x = −4, y = 3, and z = 2.
maw [93]
If you put in the substitutions it would be 2*2-(2*2*4)+(3*2)-(-4*2)+(2*4).
Simplified further by multiplying it would be 2*2-8+6--8+8
the negative 8 could be simplified further since the negatives cancel out so you'll have 2*2-8+6+8+8.
Then using the order of operations you would multiply the 2's together first to get 4 so you have 4-8+6+8+8. 
After that it's simple addition giving you an answer of -26.
I'm not sure if you're looking for the final answer or just the equation with substitutions but there's both.

!. PLEASE HELP!!! will mark brainliest!!

Matter exists in three states; <em>solid, liquid and gas.</em>

The statement that corrects the error in his table is:

<em>D. The Solids column and the gas column should be switched because solids have a definite shape and volume and gases have no definite shape or volume. </em>

<em />

<em />

Looking at the table, we have the following observations.

  • <em>The solid column shows indefinite shape (because the particles fill in the container)</em>
  • <em>The liquid column is properly cataloged</em>
  • <em>The gas column shows a definite shape</em>

<em />

Solid has definite shape, while gas doesn't.

To make corrections, Marcus needs to switch the gas and the solid column.
