Answer:
The weight of the three blades together is 
Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is equal to
we have
assume
substitute
step 2
Find the area of the 3 blades
we know that
The area of the 3 blades represent a central angle of 60 degrees, so
its a 1/6 of the area of complete circle
step 3
Find the weight of the three blades together to the nearest gram

Answer:
Step-by-step explanation to be honest probably 12 if not i’m so sorry
<span>Semicircle area = circle area / 2 = (pi*r^2)/2
16 in is the radius. Let's call the area of this semicircle s.
3.14*16^2=s
</span><span>Trapezoid area = ((base 1 + base 2) / 2) * h
Here, base 1 is 44 and base 2 is 36. The height (h) is 20. Let's call this trapezoid's area t.
(44+36)/2 *20 = t
</span>
<span>We can remove the area of the semicircle (that created by the windshield wiper) by subtracting it from the area of the trapezoid.
t - s = uncleaned area
[(44+36)/2 * 20] - [3.14 * 16^2] = uncleaned area</span>
Degree of ploynominal is the largest exponent you find, which is here the 4x to the 6th. there are only two terms here.
