Answer:
Length of the given arc AB = 7.33 in.
Step-by-step explanation:
Formula to calculate the arc length is,
Arc length = 
Where θ is the measure of central angle subtended by the arc.
And 'r' = radius of the circle
By substituting the values given in the formula,
Length of arc AB = 
= 
= 
= 7.33 in.
Therefore, length of the given arc AB = 7.33 in.
Multiply 4/5 by 3 and 2/3 by 5
4/5=12/15
2/3=10/15
