Question

given the center and the radius of a circle, write the equation describing the circle. (0,0),r=8
(x-0)^2+(y-4)^2=81
x^2+(y-4)^2=81

Answer 1

(0,0) r = 8 would be x^2 + y^2 = 64

because (x - 0)^2 + (y - 0)^2 = 8^2

Answer 2

im lost

Answer 3

I don't really know what you are asking.

Answer 4

whats the answer and how did you find it sweety?

Answer 5

What are the last two equations there for? The questions says write the equation of a circle with center (0,0) and radius 8... The answer to that is x^2 + y^2 = 64

Answer 6

i dont know thats what it says
