Question

find the length of ac

Answer 1

is the angle subtended by the arc in degrees or radians

Answer 2

\[\theta =\frac{ l }{ r },or~l=r*\theta,where,~\theta~ is~\in~radians.\]

Answer 3

degrees. degrees equals 60. AB=24ft

Answer 4

ok... so is AB the radius...?

if so the arc length

\[AC = \frac{60}{360} \times 2 \times \pi \times radius\]

the arc is a part of the circumference.

the fraction is determined by the angle/360

hope it helps
