The general equation of a circle is given by the formula
(x - h)2 + (x - k)2 = r2, where (h, k) is the center of the circle, and r its radius.
Since the center of the circle is (0, 0), the equation reduces to
x2 + y2 = r2
So that the equation of our circle is x2 + y2 = 36.

x2 + y2 = 25
x2 + y2 = 25
The equation of the circle is: (x-2)^2 + (y+3)^2 = 16
10. Equation of circle is x2 + y2 = r2. Consider: when x = 0 y2 must = 100 so y = 10 which describes a circle centre the origin, radius 10. Similarly when x = 10 y must be 0.

x2 + y2 = 49
x2 + y2 = 25
x2 + y2 = 25
x2 + y2 = 36
x2 + y2= 16
x2 + y2 = r2, the equation of a circle centered at the origin. If you want to make the circle larger, increase the radius length.
The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.
Equation of circle: (x+2)^2 +(y+3) = 49
Since the circle is centered at the origin, the equation of the circle is x2 + y2 = r2. So we have: x2 + y2 = (3/2)2 x2 + y2 = 9/4
