Answer:
x^2 + y^2 = 4
Step-by-step explanation:
The center-radius form (formally called the standard form) of a circle is
(x-h)^2+(y-k)^2=r^2 where (h,k) is the center and r is the radius.
So if we replace (h,k) with (0,0) since the center is the origin and r with 2 since the radius is 2 we get:
(x-0)^2+(y-0)^2=2^2
Let's simplify:
x^2 + y^2 = 4
The answer should be (0, 0).
I'm not sure. Hope it helps.
You can use a calculator for this. Hope it helps! :)
Answer: (-3,5) would be the orgin but if you rotated it more it would be (3,-5)
Step-by-step explanation: you can use a peace of gragh paper to do that it makes it a lot easer.
