Question

On a coordinate grid, where is the center of this circle? x2 + y2 = 2

Answer 1

Hello :
 the standard form is: (x-a)²+(y-b)²=r²
 the center is A(a,b)     r ridus
x²+y² =2
(x-0)²+(y-0)² = 2
the center is :O(0,0)

Answer 2

Answer:

center is (0,0) , radius =$\sqrt{2}$

Step-by-step explanation:

x^2 + y^2 = 2

center radius form of a circle is (x-h)^2 +(y-k)^2 = r^2

Where center is (h,k) and r is the radius

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

cener is (0,0) and radius r^2= 2

r= sqrt(2)

so center is (0,0) and  radius =$\sqrt{2}$
