Step 1:

The total length of the wiper mechanism is $\"\"$ inches.

The length of rear windshield wiper of $\"\"$ inches.

Arc radius

$\"\"$

A car’s rear windshield wiper rotates with $\"\"$ .

Convert degrees into radians.

$\"\"$

Step 2:

The area of sector of a circle $\"\"$

Area of the $\"\"$ sector is

$\"\"$

Step 3:

The area of the sector with radius $\"\"$ is

$\"\"$

Area swept out by the wiper = Area of the 125 degrees sector - The area of the sector with radius $\"\"$ .

Area swept out by the wiper = $\"\"$ .

= $\"\"$ .

Solution:

Area swept out by the wiper = $\"\"$ inches^2
