The length of an arc rounded to the nearest hundredth is 4.75units

How to calculate the length of an arc?

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
