i need help with this question please

arc ABC = 4π[tex]\frac{134}{180}[/tex]
Step-by-step explanation:
Given,
∠BOA = 51° and ∠AOC=83°
We take O as the center
So, ∠BOC = 51°+83° = 134°
To find the arc ABC
Formula,
The relation between arc and radius is, s = rθ where s be the arc and θ be the angle measured in radian]
θ degree = θΠ×[tex]\frac{1}{180}[/tex] in radian
Hence,
arc ABC = 4π[tex]\frac{134}{180}[/tex]
