Question

length of an arc of a sector of angle thita for a circle with radius r is

Answer 1

circumference of the circle with angle 360 = 2 pi r

length of the arc = thita/360*2*pi*r

Answer 2

$\ {\mathfrak{Here is your answer Hope this helps you}}$



$length \: of \: an \: arc \: of \: a \: sector \: \\ \\ = \frac{angle \: thita}{360 {}^{0} } \times 2\pi \times r$
