<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>
The right answer is 118.

Hope it will help you....
Good luck on your assignment.
First do PEMDAS
There's no parenthesis. So move on to exponent. There's also no exponents. Move on to multiplication. There it is.
12×5=60.
There's no division so now next one is addition. Hey look! There is addition.
60+55=115.
So 115 is your answer.
Which number is the under lined digit?
In a standard set of cards, the probability of drawing a red card or a face card is 73%
<h3>What is the probability?</h3>
In a standard deck of cards, there are 26 red cards. In that same deck, there will be 12 face cards.
The probability of picking either one is:
= (Number of face cards + Number of red cards) / Number of total cards
Solving gives:
= (12 + 26) / 52
= 38 / 52
= 73%
