# How do you convert r = 5 into cartesian form?

Aug 22, 2016

${x}^{2} + {y}^{2} = 25$

#### Explanation:

To convert from $\textcolor{b l u e}{\text{polar to cartesian form}}$

$\textcolor{\mathmr{and} a n \ge}{\text{Reminder }} \textcolor{red}{| \overline{\underline{\textcolor{w h i t e}{\frac{a}{a}} \textcolor{b l a c k}{r = \sqrt{{x}^{2} + {y}^{2}}} \textcolor{w h i t e}{\frac{a}{a}} |}}}$

$r = 5 \Rightarrow \sqrt{{x}^{2} + {y}^{2}} = 5 \Rightarrow {x}^{2} + {y}^{2} = 25$

This is a circle, centred at the origin with radius of 5.
