Since there are no equations following, the answer must be "none of them".
x2 + y2 = 25radius of 10?x2 + y2 = 100
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.
The radius of the circle decreases when you make the circle smaller.
The equation is: x2+y2 = radius2
The equation for calculating the area of a circle is A r2, where A represents the area and r is the radius of the circle.
