5. A circle with centre (0,0) has equation: x2 + y2 = radius2 With: x2 + y2 = 25 = 52 The radius is 5.
Type your answer here. Find the radius for a circle with the equation x2 plus y2 equals 9? ..
I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.

X2 + y2 = 100 = r2 r = 10
X2 or 2 times x?
Equation of a circle centre the origin is: x2 + y2 = radius2 ⇒ radius = √9 = 3.
