Question

On a coordinate grid, where is the center of this circle?

x² + y² = 2
A)
(-1, -1)
B)
(0,0)
(1.1)
D)
(2, 2)

Answer 1

Option B) (0,0) is the correct answer.

Explanation:

Given equation of circle is:

`x^2+y^2 = 2`

The general form of equation of circle with center at (h,k) and radius r is given by:

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

The given equation of circle can also be written as:

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

Comparing it with the general form of equation, we get

h = 0 , k = 0

So the center is (0,0)

Hence,

Option B) (0,0) is the correct answer.
