Please see the explanation.

Explanation:

square both sides:

$r^{2} = 2^{2}$ $r^2 = 2^2$

Substitute $x^{2} + y^{2}$ $x^2 + y^2$ for $r^{2}$ $r^2$

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

This the rectangular from of the equation of a circle with radius 2.

Answer 2 · 2016-12-05T18:37:42

$x^{2} + y^{2} = 4$ $x^2 +y^2 =4$

Explanation:

Write $r^{2} = 4$ $r^2=4$ . Since $r^{2} = x^{2} + y^{2}$ $r^2= x^2 +y^2$ , the given equation would become $x^{2} + y^{2} = 4$ $x^2 +y^2 =4$ in rectangular form
