Answer:

315.19

Step-by-step explanation:

Given:

  • <u>Radius</u> of the <em>cone </em>is 7.
  • <u>Height</u> of the<em> cone</em>  is 7.

To find:

The volume of a<em> cone</em> with a <u>radius</u> of <em>7</em> and a <u>height</u> of <em>7</em>.

Solution:

<em>Use the formula:</em><em> </em>V=\frac{1}{3}h\pi r^2

Result:

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

=\pi *7^2*\frac{7}{3}

≈359.18876

Now round to the nearest hundredth.

≈ 359.19

Note*

Nearest hundredth is the second digit after the decimal point.

Explanation:
______________________________________________________

 g(x) = 8x² + 9x − 7 ;

 g(4) = 8(4²) + 9(4) <span>− 7 ;
</span>
        = 8(4*4) + 36 <span>− 7 ;
</span>
        = 8(16) + 36 <span>− 7 ;
</span>
        = 128 + 36 <span>− 7 ;

Can you guys see if you can solve B) for me plz
yanalaym [24]
In the b section on this piece of paper, we can see, that this would practically be a pie graph, or if you would want to call it a graph in general. As the question stated, we see how we would want to find the perimeter of the figure. So this, sense this would only be 1/4 of the figure, we would then do 4(in) x's 4 and from this, your perimeter would give you 16(in).
