A rear windshield wiper on a car has a total arm length of 10 inches and rotates back and forth through an angle of 95 degrees. The actual wiper blade is 7 inches long. Find the area of thr windshield that is being cleaned.

  • trig - ,

    area of a circle =pi(r)^2
    since its 95 degrees 95/180=.5278
    r=7 inches
    therefore the area is 81.25

  • trig - ,

    Yea, but it isn't the entire circle so a circle area formula won't work. The equation for this area will be A= (1/2)r*Given Angle...
