Arc length is combining the formula for circumference of a circle with the central.
In polar coordinates we define the curve by the equation r fth where a th v. X f t y gt z ht x f t y g t z h t Also recall that with two dimensional parametric curves the arc length is given by L b a f t2 gt2dt L a b f t 2 g t 2 d t There is a natural extension of this to three dimensions. Here we calculate the arc length of two familiar curves. As circumference C 2pr L th 2pr 2p L th r.
