Mr. Ali, a car mechanic in Mandera County, is testing a windshield wiper on a client's car. The wiper blade is 40 cm long and it swings through an angle of 100° as it clears the windshield.
Given:
Wiper Length (r) = 40 cm
Central Angle (θ) = 100°
π = 22/7
Formula:
Arc Length = (θ/360°) × 2πr
How long is the arc that the tip of the wiper moves through? Convert your answer to 1 decimal place.
