Answer:
The length of minor arc AB is 8
Step-by-step explanation:
In this question, we are asked to calculate the length of the minor arc.
Mathematically, the length of an arc can be calculated using the formula below;
Length of an arc = θ/360° × 2πr
Where θ is the angle subtended by the arc which is 120° according to the question, r is the radius of the circle which is 4 according to the question.
Plugging these values, we have
Length of minor arc AB = 120/360 × 2 × 22/7 × 4 = 8.34 = 8 to the nearest integer
