find the equation of a circle with.
Center (0,0), radius 2
What is
x^2+y^2=4
how will that help me solve the problem
To find the equation of a circle, we use the formula:
(x - h)^2 + (y - k)^2 = r^2
Where (h, k) is the center of the circle and r is the radius.
Given that the center of this circle is (0, 0) and the radius is 2, we can substitute these values into the formula:
(x - 0)^2 + (y - 0)^2 = 2^2
Simplifying the equation gives us:
x^2 + y^2 = 4
Therefore, the equation of the circle with center (0, 0) and radius 2 is x^2 + y^2 = 4.
