Answer to Question #116100 in Trigonometry for Nyevii

Question

In a circle of radius 30 inches, a central angle of 35 will intersect the circle forming an arc of length _____.

Answer 1

1. an arc of length = L$\Delta$
2. R = 30 inches
3. $\alpha$ = 35°.

$L\Delta=(πR/180)*\alpha$,

$L\Delta=(π*R/180)*35=(π*30/180)*35=35π/6.$
