Arc Length of a Circle Arc Square formula
$n \;=\; \dfrac{ 2\cdot \pi \cdot r}{4 }$
Symbol	English	Metric
$n$ = arc length	$ft$	$m$
$\pi$ = Pi	$3.141 592 653 ...$	$3.141 592 653 ...$
$r$ = radius	$ft$	$m$

4 connecting circles (a two-dimensional figure) has four equal length arcs connecting at the vertices bound by circles.
a = b = c = d
4 arcs
4 vertexs

Area of a Circle Arc Square formula
$A_{area} \;=\; ( 4 - \pi ) \cdot r^2$
Symbol	English	Metric
$A$ = area	$ft$	$m$

$r$ = radius	$ft$	$m$

Diagonal of a Circle Arc Square formula
$d' \;=\; ( 2\cdot \sqrt{2} - 2 ) \cdot r$
Symbol	English	Metric
$r$ = radius	$ft$	$m$
$\pi$ = Pi	$3.141 592 653 ...$	$3.141 592 653 ...$
