The volume is 508.94 cm^3

volume of a cone = $\pi$ r²(h/3)

we are given the height (6cm) and radius (9cm) so we can plug in our values

$\pi$ 9²(6/3)

$\pi$ 81(2)

$\pi$ 162

since it is asking for an exact value for the volume, you can leave pi

v = 162 $\pi$ cm³

hope this helped

That’s the number is written in standard scientific notation?

Nata [24]

Option D: 3.47*10^-7 is the correct answer

Step-by-step explanation:

In order to determine the number written in standard scientific notation, first of all we have to understand how the scientific numbers are written

the scientific numbers are written in the form of:

$a*10^n$

Here

a is a number between 1 and 10 while the value of n can be only integer (positive or negative)

so,

In the given options:

Option A has a number larger than 10 in place of a so it is not in standard notation

Option B has a number less than 1 in place of a so it is also not in standard notation

Option C has a number larger than 10 in place of a so it is not in standard notation

Option D is in standard scientific notation as 1<3.47<10 and the power of 10 is integer

Hence,

Option D: 3.47*10^-7 is the correct answer

-7 x - 2y = -13 x - 2y = 11

VashaNatasha [74]

Well the first one would convert to
-2y= 7x-13 and the second one would be -2y=-x+11 and you solve from there (lmk if you need the steps) but your final answer would be. Y= -7/2x+ 13/2 and y=1/2x - 11/2

Which one of the following reasons does NOT explain why 4x+5y≠9xy?

viva [34]

<h3>The terms 4x and 5y has different variable present in it. $4x + 5y \neq 9xy$ </h3>

Solution:

Given that,

$4x + 5y \neq 9xy$

The reason is:

When we are adding terms which has exactly the same variables, we must add the constants and let the result stand with variable

Which means,

4x + 10x = 14x

But,

We cannot add terms that has different variable

Which means,

4x + 5y

Here, both the terms 4x and 5y has different variable present in it. Hence they cannot be added together

$4x+5y\neq 9xy$

{{Geomotry}} please I need help! My math grade depends on it! ;w;

lozanna [386]

This basically means that you have to multiply the x and y values by 3. So 2 time 3 is 6. And -7 times 3 is -21. So the new coordinations are (6, -21)

Hope this helped and pls mark as brainliest!
