Answer 1

What is the radius of the circle whose equation is \[x^2 + ^y2 = 9?\]

Answer 2

\[\Large x^2 + y^2 = r^2 \]Radius of a circle in this form is r.

Eg \[\Large x^2 + y^2 = 36\]the radius of this circle would be 6.

I'm bad at radius /:

Answer 4

Another example: \[\Large x^2 + y^2 = 64\]radius would be 8.
