Answer:
4 (k-3)
Step-by-step explanation:
Now, notice the picture below
is really just one rectangle and a circle, well, half a circle or a semi-circle
so.... if you get the area of the whole rectangle, 16*19
and subtract, the area of half the circle, you end up with the shaded area
since, what you'd be leftover is, the rectangle, with a semi-circular hole, that was subtracted
![\bf \textit{area of a circle}\\\\ A=\pi r^2\qquad \begin{cases} r=radius=\frac{diameter}{2}\\ ----------\\ diameter=16\\ r=\frac{16}{2}=8 \end{cases}\implies A=64\pi \\\\ -----------------------------\\\\ \textit{shaded area}\implies (16\cdot 19)\quad -\quad 64\pi](https://tex.z-dn.net/?f=%5Cbf%20%5Ctextit%7Barea%20of%20a%20circle%7D%5C%5C%5C%5C%0AA%3D%5Cpi%20r%5E2%5Cqquad%20%0A%5Cbegin%7Bcases%7D%0Ar%3Dradius%3D%5Cfrac%7Bdiameter%7D%7B2%7D%5C%5C%0A----------%5C%5C%0Adiameter%3D16%5C%5C%0Ar%3D%5Cfrac%7B16%7D%7B2%7D%3D8%0A%5Cend%7Bcases%7D%5Cimplies%20A%3D64%5Cpi%20%5C%5C%5C%5C%0A-----------------------------%5C%5C%5C%5C%0A%5Ctextit%7Bshaded%20area%7D%5Cimplies%20%2816%5Ccdot%2019%29%5Cquad%20-%5Cquad%2064%5Cpi%20)
now... let's say, you get an amount of hmmm [?]
ok, how much is that in percentage? well, 16*19 is 304
so, if we take 304 as the 100%, how much is [?] in percentage?
![\bf \begin{array}{ccllll} amount&\%\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ 304&100\\ \boxed{?}&x \end{array}\implies \cfrac{304}{\boxed{?}}=\cfrac{100}{x}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccllll%7D%0Aamount%26%5C%25%5C%5C%0A%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%26%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5Ctextendash%5C%5C%0A304%26100%5C%5C%0A%5Cboxed%7B%3F%7D%26x%0A%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B304%7D%7B%5Cboxed%7B%3F%7D%7D%3D%5Ccfrac%7B100%7D%7Bx%7D)
solve for "x"
You multiply 1500 by 3 percent and get 45. 1500-45 = 1455. So $1455
The answer is 0 because any number - itself is equal to 0
