Question 550720
A certain windshield wiper is 10 inches long and it is attached at the outside end( opposite the center of rotation). If the windshield wiper sweeps through a 180 degree angle, what is the area cleaned by the rubber blade? State your answer in terms of pi.

Not clear what you mean about the "outside end"

Area of a circle = {{{pi*r^2}}}
r = 10 inches
1/2 the circle = 100pi/2
= 50*pi sq inches
