The length of an arc rounded to the nearest hundredth is 4.75units
<h3>How to calculate the length of an arc?</h3>
The formula for calculating the length of an arc is expressed as:
L = rtheta
where
r is the radius = AB = 4 units
theta is the central angle = <ABC = 68 degrees
Substitute
L = 4(68π/180)
L = 4.75units
Hence the length of an arc rounded to the nearest hundredth is 4.75units
