Explanation:
Your question seem incomplete; however, I'll give a general guideline you can follow when solving for length of an arc.
The length of an arc is calculated as follows;
Length = θ/360 * 2πr
Where θ is the central angle and r is the radius
Take for instance, θ = 60 and r = 6cm
The solution will be;
Length = 60/360 * 2 * 3.14 * 6cm
Length = ⅙ * 2 * 3.14 * 6cm
Length = 6.28cm
So, for any values of θ and π, you'll get your results when you apply the above formula.
