It should be noted that the answer is not part of the given options, however the equation of the circle is x^2+y^2 = 4
Equation of Circle
Given Data
radius = 2
We know that the expression for the equation of a circle is given as
(x-h)^2 + (y-k)^2 = r^2
x2-
substituting our given data into the expression we have
(x-0)^2 + (y-0)^2 = 2^2
x^2+y^2 = 4
What is the Equation of a Circle?
When a circle is a closed curve that is drawn from the fixed point, all the points on the curve are having the same distance from the center point of the center. The equation of a circle with (h, k) center and r radius is given by: (x-h)^2 + (y-k)^2 = r^2
