Ashley derived the formula for the arc length .
Given :
Ashley is studying circle O,
She wrote few steps that is given below
Given steps are
STep 1 : θ/2π=s/2πr
Step 2: θ(2πr)/2π
Step 3: s=θr
From the given diagram , we know that
θ is the angle of a sector .
The radius of the circle is 1 unit
's' is the length of the arc length
formula for the arc length 's' is central angle times the radius of the circle .
s=θr is the formula for the arc length
Ashley derived the formula for the arc length .
