The arc length of the sector AB of the circle will be 12.56 cm. Then the correct option is A.
What is the arc length of the sector?
Let r is the radius of the sector and θ be the angle subtends by the sector at the center.
Then the arc length of the sector AB of the circle will be
Arc = (θ/360°) 2πr
The radius of the circle is 12 cm and the sector angle is 60°.
Then the arc length of the sector AB of the circle will be
AB = (60°/360°) 2π × 12
AB = 3.14 × 4
AB = 12.56
The arc length of the sector AB of the circle will be 12.56 cm.
Then the correct option is A.
