The process of desertification presents a serious impact on the well-being and health of the people living
in the areas affected by droughts and land degradation
on an unprecedented global scale. The worst situations

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
