It the wiper blade (and arm) made a full rotation, 2 circles would be formed.
One small circle with radius
b, and a larger circle with radius
a+b.
The areas of these 2 circles are respectively:

and

120° is 1/3 of a complete angle 360° which form a circle, so the areas formed by the arm of length b, and the arm + the wiper blade (a+b) are:

and

in squared respectively.
the actual wiped area is

(in squared)
Area of the window is 54*24= 1296 (in squared)
thus, the ratio of the wiped area to the whole area of the window is 351.7/1296=0.271
Converted to percentages, this is 27.1%
Answer: 27.1%
The first option, because if it’s 291 yards and 1/4 BELOW (below: meaning negative because you are under the usual sea level).
-291 (1/4)
Hope this helped!
Answer:
3 blankets.
Step-by-step explanation:
First, you do 6/2 and you get 3 yards of fleece for 1 blanket. 9/3 is 3 so 3 times 1 is 3.
So there are 3 blankets for 9 yards of fleece.
