x2 + y2 = 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
Equation of the circle: (x+1)^2 +(y+3)^2 = 25
It is (x + 1)2 + (y - 3)2 = 42
(x+3)2 + (y+4)2 = 4
x2 + y2 = 25
x2 + y2 = 25
x2 + y2= 16
x2 + y2 = 49
x2 + y2 = 36
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.
