Find an equation of the circle that has center (-4,3) and passes through (6,-4).

kumpel [21]

Answer:

$(x+4)^2+(y-3)^2=149$

Step-by-step explanation:

The equation of a circle is $(x-h)^2+(y-k)^2=r^2$ where $(h,k)$ is the center of the circle and $r$ is the radius of the circle.

Given that $(h,k)\rightarrow(-4,3)$ and it passes $(6,-4)$ , their distance between each other must the radius of the circle, so we can use the distance formula to find the radius:

$d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\\\d=\sqrt{(-4-3)^2+(6-(-4))^2}\\\\d=\sqrt{(-7)^2+10^2}\\\\d=\sqrt{49+100}\\\\d=\sqrt{149}$

Therefore, if the length of the radius is $r=\sqrt{149}$ units, then $r^2=149$ , making the final equation of the circle $(x+4)^2+(y-3)^2=149$

V=pi r^2 h solve for pi<br><br>please help asap<br>will mark brainliest

kogti [31]

Answer:

$\pi=\frac{v}{hr^2}$

Step-by-step explanation:

So we have:

$v=\pi r^2h$

And we want to solve for π.

First, divide both sides by h:

$\frac{v}{h}=\pi r^2$

Now, divide both sides again by r²:

$\pi=\frac{v}{hr^2}$

And this is our answer :)
