The upper arc is longer than the lower arc by inches.
Step-by-step explanation:
Since both the arcs are made by the same wiper blade, hence the angle of the arc would be the same.
The radius of upper arc= 22 inch
The radius of the lower arc= 5 inch
Angle made by the arc= 135°
We know that length of the arc= (angle made/360)*2πr
Where r is the radius of the arc
The difference in the arc length has been due to the difference in radius of the arcs.
Hence, the difference in the radius would be equal to the difference in arc length.
Difference in wiper radius= 22-5= 17 inch
Putting the values together
arc length= (135/360)*2*3.14*17
arc length= 40.035
The difference in arc length=40 inches (rounded off to the nearest whole number)
