write a code to draw a circle based on slide $13$: chapter $2$ write a code to draw a circle based on slide $13$: chapter $2$

$-$Input: $($cx$,$cy$)$ is the center, $R$ is the radius, and $S$ is number of sides

$-$Output: a regular polygon of $S$ sides

$-$Steps

$1.$Step $=2\frac{}{S}$

$2.$Set angle $=0$

$3.$Compute $p0=(cx+r*Cos,cy+r*Sin)$

$4.$Compute step

$$Input: $($cx$,$cy$)$ is the center, R is the radius, and S is number of sides

$$Output: a regular polygon of S sides

$$Steps

$1.$Step $=2\backslash$pi $/$ S

$2.$Set angle $\backslash$theta $=0$

$3.$Compute p$0=($ cx $+$ r $*$ Cos $\backslash$theta $,$ cy $+$ r $*$ Sin $\backslash$theta $)$

$4.$Compute p$1=($ cx $+$ r $*$ Cos $(\backslash$theta $+$step$),$ cy $+$ r $*$ Sin $(\backslash$theta $+$step$))$

$5.$Plot the line between p$0$ and p$1$

$6.\backslash$theta $=\backslash$theta $+$ step

$7.$Go to step $3$ if $\backslash$theta has not exceeded $2\backslash$pi
