I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.
I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.
Equation of a circle centre the origin is: x2 + y2 = radius2 ⇒ radius = √9 = 3.
5. A circle with centre (0,0) has equation: x2 + y2 = radius2 With: x2 + y2 = 25 = 52 The radius is 5.
Standard equation for a circle centred at the origin is x2 + y2 = r2 where r is the radius of the circle. If you increase the size of the circle then the radius must increase, so r2 will be larger. eg a circle of radius 2 has the equation x2 + y2 = 4, if the radius increases to 3 then the equation becomes x2 + y2 = 9
If that equals 16 then the radius is 4
x2 +y2 = R2 =16 = radius 2 R = 4

x2 + y2= 16
4
