x2 + y2 = 2
If that means = 36 then then the radius of the circle is 6 units
x2 + y2 = r2, where r is the radius.
It is x2 + y2 = 4
I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.

x2 + y2 =x2 + y2 = 5x2 + y2 = 10x2 + y2 = 25
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.
The equation of circle is (x−h)^2+(y−k)^2 = r^2, where h,k is the center of circle and r is the radius of circle. so, according to question center is origin and radius is 10, therefore, equation of circle is x^2 + y^2 = 100
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
