Question

What is the equation of the following graph?

Answer 1

i guessed x^2+y^2=100? but idk for sure

Answer 2

x^2 + y^2 = 5^2

Answer 3

its not the diameter that you square, its the radius

Answer 4

x^2+y^2=5^2

Answer 5

@pitachip & @Diogo thanks can you guys explain what i did wrong.. thanks again

Answer 6

you did x^2+y^2=10^2 instead of 5^2.

The formula of a circle in cartesian coordinates is: (x - h)^2 + (y - k)^2 = r^2

where H is the horizontal distance to 0 and K is the vertical distance to 0.
R stands for radius. wich is = 5

Answer 7

@Diogo thanyou so much!!! i understand now!
