The equation of a circle is

sergij07 [2.7K]

Answer:

The answer is

<h3>center = ( - 7 , - 1)</h3><h3>radius = 6</h3>

Step-by-step explanation:

The general equation of a circle is given by

where the center of the center of the circle is given by

From the question the equation is

x² + y² + 14x + 2y + 14 = 0

Comparing with the general equation above we have

2g = 14 2f = 2

g = 7 f = 1 c = 14

So the center of the circle is

The radius of a circle is given by

$r = \sqrt{ {g}^{2} + {f}^{2} - c}$

where

g = 7

f = 1

c = 14

Substitute the values into the above formula

That's

$r = \sqrt{ {7}^{2} + {1}^{2} - 14 } \\ r = \sqrt{49 + 1 - 14} \\ r = \sqrt{36}$

we have the final answer as

<h3>radius = 6</h3>

Hope this helps you

Write six and seven hundred one-Thousands in standard form

mestny [16]

Since r = h, we can substitute that into the equation
<span>V = pi * r^2 * r = pi * r^3 </span>

<span>Since we know the volume, we can put that in too. </span>
<span>64 pi = pi * r^3 now let's divide both sides by pi. </span>
<span>64 pi/pi = pi * r^3/pi </span>
<span>64 = r^3 </span>
<span>cuberoot(64) = r </span>
<span>cuberoot (2^6 )=r </span>
<span>4 = r</span>
