Arc length = 4.28 cm.
Arc length is the distance between two points along a section of a curve.
circumference of a circle of radius r is C = 2πr,
and central angle = 360 degrees.
circumference = 28 cm.
28 cm =2πr
28= 2*3.14*r
28= 6.28*r
r= 4.46 cm.
Arc length, s = r[tex]\theta[/tex]
[tex]\theta[/tex] =55 degrees,
s = 4.28 cm.
