Question

Someone please help me! Write the equation in standard form!

Answer 1

`x ^2 + y^2 = 36`

Explanation:

Center of the circle (h, k) =(0, 0)

Radius of the circle (r) = 6 units

Equation of circle in center radius form is given as:

`(x-h) ^2 + (y-k) ^2 = r^2`

`(x-0) ^2 + (y-0) ^2 = (6)^2`

`x ^2 + y^2 = 36`

Answer 2

x^2+y^2=6^2

Explanation:

The equation of a circle is (x-h)^2+(y-k)^2=r^2

where h is the x coordinate of the center, k is the y coordinate of the center, and r is the radius of the circle.

We can see the center is on 0,0, and the radius is 6, so our equation is

(x-0)^2+(y-0)^2=6^2

or

x^2+y^2=6^2
