Answer :
We find that what fraction of the circumference is this arc 27.75 cm.
The length of the arc of a circle of radius r that subtends an angle of θ
in radians at the center is calculated using the formula:
Arc length=rθ
What fraction of the circumference is this arc?
An arc subtends a central angle measuring 5π/6 radians.
Let arc length be s then,
s = rθ = 10.6 * 5π/6 = 27.75 cm
