Iwill give brainlist if i get enough answers how do i find the radius someone me

r=7

Step-by-step explanation:

We have the equation

(x+5)^2 + (y+8)^2 =

We know that this is equal to the radius squares

(2+5)^2 + (-8+8)^2 = r^2

We know a point  on the circle (2,-8)

Substitute this point into the equation

(2+5)^2 + (-8+8)^2 = r^2

(7)^2 + (0)^2 = r^2

7^2 = r^2

The radius is equal to 7

the solution is h=10 because you add 9 to each side of the equation.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
