$x^{2} + y^{2} = 9$ $x^2+y^2=9$

Explanation:

$Reminder$ $color(orange)"Reminder"$

$∙ r = \sqrt{x^{2} + y^{2}}$ $• r=sqrt(x^2+y^2)$

$\Rightarrow \sqrt{x^{2} + y^{2}} = 3$ $rArrsqrt(x^2+y^2)=3$

$squaring both sides$ $"squaring both sides"$

$\Rightarrow x^{2} + y^{2} = 9 \leftarrow in rectangular form$ $rArrx^2+y^2=9larr" in rectangular form"$

$this is the equation of a circle, centred at O, with radius 3$ $"this is the equation of a circle, centred at O, with radius 3"$
